Just stop spreading fake mumbo-jumbo such as this.

ted, on June 24th, 2010 at 3:36 am

Ted – as noted I tried this on my iPhone 3G last night and it did make a difference. It does make sense that clearing all RAM and caches can improve performance. Have you tried this on an iPhone 3G before making a snarky comment?

Adam Rosen, on June 24th, 2010 at 3:51 am

hi there,
a normal shutdown and restart did the trick for me after updating my 3G. after updating iOS it was definitive slower.
i just tried your way (though i was happy with speed) but cannot see any improvements. maybe ur right with RAM cleaning, but the restart should do.

derschwarzeritter, on June 24th, 2010 at 4:02 am

So, the best way to get iOS4 to work right on a 3G is to do a double hard reset, ostensibly to clear all of the short-term memory? How frequently? Once a week? Every time it slows down?

In some ways, I really wish that they would have not allowed the 3G to run iOS4.

eric, on June 24th, 2010 at 4:21 am

For me it worked. I made ‘regular’ restart after upgrade to iOS4 and ‘hard reset’ now. The question is for how long this will help?

marcin, on June 24th, 2010 at 4:27 am

Yep, helped a lot but it take 2 hard resets….

alpacaguy, on June 24th, 2010 at 4:28 am

Glad someone else noticed the slow performance; thought it was just my phone! Tried this hard reset and seems to have improved performance

Roy, on June 24th, 2010 at 4:32 am

Everything to terminate that laziness from iOS4 Update…

Thiago, on June 24th, 2010 at 4:45 am

Is the slow down problem just with 3G or does it affect the 3GS also?
Thanks in advance for advice

Vern, on June 24th, 2010 at 5:43 am

just downgrade to OS 3. that’s what i did after being bored of how unusable OS4 beta 3 was (i had enabled mutlitasking and background images, which was a mistake). I downgraded also so i could use MyWi which doesn’t support OS4 (not only ’cause of the speed issue), but 3 is so much faster. I must also note that i’ve moved most of my apps to the iPad and am using the phone more as a phone than a do it all device.

andy, on June 24th, 2010 at 5:44 am

what is battery life like?

bob, on June 24th, 2010 at 6:05 am

I was having a heck of a time with iOS 4 on my 3G; I ended up doing a restore and setting the phone up from scratch (opposed to a restore from backup). Things are working great now:

Brandon Martinez, on June 24th, 2010 at 6:20 am

Vern – at the moment this problem primarily seems to affect only the iPhone 3G. Many 3GS users are reporting no problems or an increase in performance.

Adam Rosen, on June 24th, 2010 at 6:38 am

Hey, thanks very much for the tip! I was noticing the same thing on my 1st -gen 3G and it has been driving me bananas. I don’t want to cough up the fundage for the new Iphone 4 but was fearing I would need to due to this (and the insanely short battery life). Do you know if they’ve fixed the battery issue on the 4?

Diane, on June 24th, 2010 at 8:04 am

i am doing this now – but how do you go back to the previous version – i cant handle the slowness and buggy-ness of the phone.

thanks

b, on June 24th, 2010 at 8:36 am

It worked for me!! Thanks

Chuy, on June 24th, 2010 at 8:51 am

Did the Hard Reset for my iPhone 3g after getting the OS4 but some apps tend to shut down after opening it and also it was still slowww. Do hope Apple would fix this… or are they wooing us to get the new iPhone 4. Maybe. Thanks for the tip.

Don, on June 24th, 2010 at 8:58 am

This helped on my iPod Touch 2nd Gen! It was so slow after the update it was unusable. Hard rebooted twice and now its back to its normal self!

Thanks guys

Ben Ridley, on June 24th, 2010 at 9:00 am

Sorry guys, but i didn’t notice any increased performance on my molasses in winter slow 3G.

Can’t wait for iPhone 4. I’m in Canada though (eh?) so who knows when we’ll get them?

Good try though.

.

Vanmacguy, on June 24th, 2010 at 9:20 am

iOS 4 works perfectly in my iPhone 3G[S] – 32GB (White)

Cesaro, on June 24th, 2010 at 9:44 am

seems to have made mine even slower!!!! =S

Ben, on June 24th, 2010 at 9:57 am

Looks like mine behaves better now.

Ferd, on June 24th, 2010 at 10:08 am

The 3GS actually speeds up a little bit with iOS 4, but I have noticed that occasionally it will start up and start frantically trashing battery life, even without background activity occurring. In those cases, a double hard restart gets back on the right track to have a saner degree of battry consumption.

Pete Mortensen, on June 24th, 2010 at 10:46 am

Blimey my 3G with OS4 is sooooooo slow lmao…..zzzzzzzzzzzzzzzzzzz. Done the hold down restart thingy now 4 times with a slight improvement.

Glenn, on June 24th, 2010 at 2:54 pm

I had tried single hard reset, no help. Double hard reset seems to have helped.

But then again, back before the iOS4 update, I was in the habit of hard-resetting when it seemed slow. I think it was even slower (and more jerky) under iOS4, but can’t really swear to it.

jrep, on June 24th, 2010 at 4:15 pm

After iOS4 update my 16g 3G was slowwwwwww, then did a restore from backup and a hard reset now it works fine. Still took like 2 1/2 hours but all seems good now.

jj, on June 24th, 2010 at 9:45 pm

I can confirm this surprising trick does work on the 3G. After the update to iOS4 MMS for me have been painfully slow now its zippier than before! Especially after jailbreak and enabling all the stuff apple left out!

Nathan, on June 24th, 2010 at 11:32 pm

Yep, this certainly helped. My 3G seems to be back at the IOS3 speed. Thanks for the tip

Dinky, on June 25th, 2010 at 12:26 am

im in the process of trying this, but did this work with ibooks as well?? because trying to use that is horribly slow and nearly impossible.
thanks in advance

Kimbo, on June 25th, 2010 at 5:50 am

ibooks is noticeably faster too!!!!
thank you!!!

Kimbo, on June 25th, 2010 at 6:48 am

Yes!! Thank you very much this worked for me too after tearing my hair out for the last week or so!!

ROSS, on June 25th, 2010 at 12:37 pm

Seems to be helping on mine as well. Still a bit slower than it was on 3.1.3, but A LOT faster than it had been.

Siamac, on June 25th, 2010 at 1:42 pm

Downloading OS4 made me hate my iPhone for the first time ever…Did 2 hard restarts, still no faster and apps still crashing This sucks!!!!!!

Jamie, on June 25th, 2010 at 2:36 pm

2x hard reset worked for my 3g w/ ios4 also.
Thanks

corby, on June 25th, 2010 at 5:25 pm

Was interested in what this guy was saying so I tried his suggestion. I don’t think it has anything to do with clearing RAM and caches though. I am running verbose boot which allows me to see what is going on during the boot process. What I noticed is that after a hard reset a kind of check disk program runs fixing errors in files and directories, apparently quite a few in mine. The second hard reset did the same thing but found no errors so completed much quicker. I have noticed a slight improvement in performance. Just have to remember though that while this is a great phone it ain’t no high end computer.

Cory, on June 25th, 2010 at 6:51 pm

Works for my iPhone 3G 8GB

Jamie – If 2 hard resets didn’t work try 3 instead. If that still doesn’t work for you then go buy a new hardware. Stop whining.

Douc, on June 25th, 2010 at 7:16 pm

The 2 hard resets workd on my ipgone 3G…b4 everything would take longer to load but now its cool..my iphone is jailbroken btw

Odia, on June 25th, 2010 at 9:57 pm

Thanks for all the feedback folks – looks like we’ve stumbled on to something. The speed improvement seems the greatest right after the second hard reset. My phone has slowed a bit again after a couple days, but not nearly to the same crawl as before.

Cory – interesting that you found a check disk program running, a la fsck I assume. That suggests possibly a disk (or flash RAM) fragmentation issue. I think the small amount of working RAM in the 3G may also be contributing to the problem.

Adam Rosen, on June 25th, 2010 at 10:28 pm

Thanks for the tip. My iPhone 3G is running much faster now. It was really slow and sluggish earlier, but after two hard resets, its back to its original pace.

Thanks a lot !!!!!

ilhaan, on June 26th, 2010 at 6:37 am

That solved the problem, but only for a few days, now it’s slow again.

iOS 4 on iphone 3g = Worst upgrade ever!

Fredrik, on June 26th, 2010 at 8:18 am

The double hard reset worked on my 3G. It’s still not on a par with a 3GS, but I actually get startup animations when I tap an app icon. Before that, the icon was greyed out and the whole phone froze for a few seconds.

Thanks you!

Jannis, on June 26th, 2010 at 8:29 am

Did not work for me. Everything is slow to open and close especially Google Maps and Mail.

Evilgenious, on June 26th, 2010 at 8:37 am

It works for me! Yippee! Thank you for making this post. (:

Wanling, on June 26th, 2010 at 11:23 am

2 hard resets, nothing. Read again all the posts, backed up and restored in iTunes and the 3gs works great. Thanks guys

Jan, on June 27th, 2010 at 1:27 am

Thank you for the tip. My sluggish 3G is far more responsive after the double reset. A small price to pay for the ability to run the new features.

Speakhead, on June 27th, 2010 at 5:24 am

This makes no sense. There is a reason why the ram got overused in the first place. 128mb vs 512mb…. thats the problem right there. The iPhone 4 probably has even more ram. Just cant fill 1 gallon of water in a pint glass. Apple never should have offered this for the 3g.

Sean, on June 27th, 2010 at 11:55 am

Whether they should or shouldn’t have offered iOS4 to 3G users remains irrelevant to the fact that this little trick seems to have saved my beloved 3G from ending up in the blender, much happier now, thank you very much

Ed, on June 27th, 2010 at 4:43 pm

After updating my 16Gb 3G to iOS4 I had a strange issue with the mail client using exchange and pop accounts, the email header and first line of content would appear in the main mail screen and when you opened the email not content would be displayed. After resetting twice it was all good. Thanks.

Jason, on June 27th, 2010 at 6:40 pm

Worked well for me and my phone is much faster. Prior to doing the Hard Reset I dramatically increased the amount of available memory. Not sure whether this helped or not but the phone is back up to speed again.

John Townsend, on June 27th, 2010 at 10:40 pm

Had to downgrade mine, missed several calls because the iphone would not respond, even with the double-reboot method!

Now that it is back on 3.1.3, sad as can be without folders. Can only hope my new shiny iPhone 4 arrives here in Germany soon…



Dan, on June 28th, 2010 at 3:00 am

it did work for my 3G ! (double hard reset)
thank you!

Joanne, on June 28th, 2010 at 5:04 am

Thank you very much for this tip! My phone does run much better now. I was getting angry with it’s performance: I was losing calls, could not get maps to work faster when I needed it, etc. But now it works much better.

AA Taxi St Louis, on June 28th, 2010 at 9:25 am

This definitely works, I’ve just done it on mine. I noticed a considerable slow-down after installing iOS4 – this makes it super-perky. I just did two hard restarts one after another which didn’t take too long. iBooks was probably the most notably fastest by a long shot, it just loads instantly now. Thanks for the tip, will tweet this later.

Kezzer, on June 29th, 2010 at 3:14 am

Nice. Mine hit ‘restore mode’ before I did this. First time I ever crashed it! Reset double-hit worked here, too.

Adam, on June 29th, 2010 at 8:15 am

Yes, its work after 1 hard reset!

Thank you very much

Éric, on June 29th, 2010 at 7:50 pm

thanks for this. i was thinking about restoring the phone to factory settings just to get rid of ios4. it took two hard resets but it seems to be back up to speed.

Chris, on June 29th, 2010 at 9:06 pm

I had an issue on my 3GS on iOS4 were the iPod music App would launch but then bomb out straight away. I tried a normal reset but this didn’t fix it. Performing your Hard reset tip though worked a treat. Thanks for the tip saved me having to restore my iPhone (so tedious). Obviously some resets are better than others!!!

Zander, on June 30th, 2010 at 12:20 am

A godsend! I spent hours searching the web for a solution to my 3G’s post-iOS4 sudden sluggishness. Finally an answer!

Judith, on June 30th, 2010 at 4:20 am

This trick gave me about 15mo of memory, GREAT! (from 2 to 17)

Francis, on June 30th, 2010 at 6:37 am

The Hard Reset of my 3G phone noticeably improved the speed of the 4.0 software! I did the Hard Reset 2 times and just like magic my phone was back to its old speed. No more sluggish response. Why the apple genius didn’t know this is beyond me! Spread the world to all 3G peeps!

Bryan Richardson, on June 30th, 2010 at 10:25 am

It worked for me too, thank you!

Eduardo, on June 30th, 2010 at 7:47 pm

unfortunately this is my 4th time…and nothing…i will have to downgrade

juice, on July 1st, 2010 at 12:20 am

I did the double/treble hard reset and immediately old girlfriends started calling. I noticed new hair growth in a prominent bald spot on my pate, and somehow I fit into the pants I wore to my wedding ten years ago. I was able to decrypt and burn a Blu-Ray disk with my phone while watching a Youtube HD video on my 3G.

It actually does make a difference…defraggler for iOS anyone?

: )

neal, on July 1st, 2010 at 2:01 am

Mail, photos, even iPod have been suffering since I upgraded.
Compound this with the non-availability of the iPhone 4 in backwoods like Ireland and I’m left really frustrated. Hope this reboot thing works. What was the point in offering the upgrade?

Lar, on July 1st, 2010 at 5:50 am

hey everyone,
same problems here with iPhone 3G running iOS4, with an additional issue… several of my apps don t work anymore, but my biggest problem is that i actually lost some very important data. i use an app QuickVoice that i use to record meetings, interviews, etc. more then a half of my recordings are lost, some of which were very important to me! after the backup, upgrade and restore, my phone suddenly had about 5GB extra space. i m very frustrated for losing my important recordings and am convinced that all these issues are no accident. i m sure that the point of this is for people to get frustrated by their “obsolete” phones and to make them hurl to the shops to get the new iPhone 4.

manutt, on July 1st, 2010 at 6:20 am

Was very skeptical about this but I tried it anyhow in utter desperation. Bloody hell it worked! Two reboots were required and now my iPhone is just like it used to be. Did it 3 days ago and it’s still fine. How did somebody ever discover this fix – the power of prayer maybe?

Peter, on July 1st, 2010 at 8:38 am

I do the reset, it improves a little, but it takes forever to restart!

Jose Betancur, on July 1st, 2010 at 9:02 am

I concur. The first hard reboot didn’t change anything. After the second reboot things were much quicker. Thanks for the tip!

Steve, on July 1st, 2010 at 9:05 am

Worked like a charm..a lot faster Thanx mate!

Branimir, on July 1st, 2010 at 12:03 pm

After the upgrade to iOS 4 on my 3G 8GB I was beating myself up for being an early adopter of this “upgrade” (really Apple??). I didn’t diserve the glacial performance of iOS4 on 3G, and the recharging of the phone twice a day (no one does… ok, well maybe someone at Apple does for having not tested it!)

I was skeptical and willing to downgrade to 3.1.3 on 6/25 when I found this post. I decided to give it a try (heck! 3 minutes doing two hard resets beats 3 hrs I would ‘ve spent downgrading and rebuilding my settings). I read the instructions twice – “measure twice cut once” people! – held my breath and did the resets.

I am happy to report that it did in fact work on my 3G 8GB, and the phone operates as it did pre-”upgrade” (again… really Apple??). While I can’t say it is speedier than 3.1.3, I also cannot say it is any slower anymore. I also feel that it is not running as hot as it was. I won’t say the battery is back to pre-”upgrade” (come on Apple, admit it is a downgrade already!) levels, but at least it lasts for the day.

I held off posting for a few days, to make sure that it wasn’t a placebo effect… and I am convinced that it isn’t. I also hope this is a permanent fix.

I wish all other 3G users suffering from the glacial effects of iOS 4 have the same results I did with “Ron L’s 3G Glacial Fix”!

Oh, and thank you Mr. Rosen for listening to Ron L’s suggestion and making this post! I owe you guys 3 hrs of my time for not having to spend installing 3.1.3 back – now that would be an upgrade Apple!

Gus, on July 1st, 2010 at 6:40 pm

Hi all,

Found this post and decided to give it a shot.

I was able to get it going after a 3rd hard reset and things seemed to
get better. But after reading other posts i found a suggestion refering
to the home screen wallpaper causing the slowness reported.

I have ( of course ) a 3G jailbroken with multitasking and wallpaper enabled.
what i did was follow this guide

http://www.iclarified.com/entry/index.php?enid=8916

and doing it the other way around ( disabling wallpaper ) now my
3G is at full speed again and with multitasking!!!

Hope this helps someone

L8r

voidRunner, on July 2nd, 2010 at 5:57 am

Does anyone know of a lawsuit by 3G owners against Apple?

Shaman, on July 5th, 2010 at 2:57 am

Class action lawsuit, anyone?

Jonny, on July 6th, 2010 at 6:20 pm

lol at the first comment saying this is fake mumbo-jumbo. This is a real issue, maybe we aren’t holding it right….

I ran into a stranger using his iPhone, he also had the same issue after the “update”

Jonny, on July 6th, 2010 at 6:23 pm

There is much, much easier way to clear RAM on iPhone!!!

Just turn it off correctly. Then press both Home and Power (Sleep/Wake) buttons and hold it till the Aplle sing appears, still hold it….Aplle sign disappears and appears again – release buttons and …that is all. It is propper and 100% safe way to clear RAM.

Cheers.

Dosa, on July 8th, 2010 at 2:01 pm

Dosa – I suspect both methods are variants of the same thing. It may work faster your way though, good to know. What appears to be getting cleared is the iPhone’s non-volatile RAM, not the normal working memory.

Adam Rosen, on July 8th, 2010 at 2:53 pm

I had the same slow response problem with iOS4 on a 3G – very annoying. I performed the double hard reset as per the article, and it appears to have helped a lot. As test operations, I used the “on” slider and opening “settings” – both were initially quite slow, and both now appear to be similar to response times seen with the earlier OS. …Still want a 4 though.

Charlie, on July 10th, 2010 at 2:58 pm

Hi, I was becoming frustrated with my 3G after upgrading to OS4. I was about to give in and buy a new iphone (as I have had it 2 years) until I read your tip. It has done the trick nicely. I am back in love with my 3G and have passed on the tip to two of my colleagues.
Thank you for taking the time to post the tip.

Debbie, on July 12th, 2010 at 6:05 am

Thanks…I was complining about how the perfomance had degraded on my iphone 3G since the last upgrade and the iphone Guru next to me performed the double hardware reset in one blink of an eye, I confirm that there is definitely a difference in system performance all be it perhaps its not a permanent solution but I am satisfied, if you have any questions pertaing to the iphone just ask gqsguru.fr and he will show u the way

moetown, on July 13th, 2010 at 6:55 am

Tryed this many times now.. no change.. Please – a guide to downgrade from 4.0 for 3G owners… need it … Anyone ?

Pecker, on July 13th, 2010 at 11:02 am

LifeHacker has this guide to downgrading to iOS3 (not a trivial procedure):
http://lifehacker.com/5572003/how-to-downgrade-your-iphone-3g%5Bs%5D-from-ios-4-to-ios-313

Adam Rosen, on July 13th, 2010 at 3:51 pm

Hi All,
I up graded my 3GS ( 32 GB) to iOS4 and started to suffer all kind of problems, worst being battery life which went down by around 40%. Applications stopped working, ipod would not open and geneally the phone speed strated to crawl. What I did was delete all applications, did 2 hard resets, loaded the applications again ( Note that in the itune store they tell you now which application is tested on iOS4), dowload only those which are tested. The phone is not faster but atleast is back to normal.

Tashfeen Qayyum, on July 14th, 2010 at 10:00 am

The hard resets seem to work, but then, for me any way, the performance quickly degrades over the next day or two. At best, this is a temporary solution that may need to be done daily for it to be effective. My iPhone 3G, which is not even two years old, is almost unusable on iOS4.

Steve, on July 14th, 2010 at 10:32 am

Damn! I followed your advice and it worked after one boot. I hope it holds up because I love my Iphone.

steve r, on July 16th, 2010 at 11:09 am

ridiculous…..
+WTF is with all of positive response!? Who are the people that accomplished anything by doing this!?

zac, on July 16th, 2010 at 7:24 pm

I think we have a WINNER!
I found a thread to fix slow os4 for 3g… It said to turn off MMS and restart. (that’s it)
I have opened and closed multiple apps since doing this and it’s been about a half hour of normal phone use, so far, (crossing fingers) no problems! I’ve gotten a notable increase in running speed. Go under: >settings>messages>mms messaging> (turn off) Reset phone. (I did two hard resets previous to this, so for me it was just a regular reset.
I have read so many posts and didn’t want to downgrade so finding this was a great relief. Please let everyone know if this works for you too…

@martintippet, on July 22nd, 2010 at 7:07 am

Martin – I’ve read that turning off MMS messaging, and also disabling Push for email and calendar events (use Fetch instead), has helped for some users. Certainly worth a try. In my case I’ve had MMS messaging off all along so the performance increase from the Double Hard Reset was separate.

Adam Rosen, on July 22nd, 2010 at 4:43 pm

Between the erratic iPhone 3G performance, the phony reception bars that Apple just got nailed on, and the “new & improved” iPhone 4 that needs to be duct-taped before the reception is acceptable, I wonder what the H is going on with Apple? Downhill slide, anyone? I’m getting a Droid. To heck with my 3G.

Thomas John, on July 22nd, 2010 at 10:16 pm

Worked for me on my 3G. Went from super slow and unresponsive to quick with one reset.

Thanks guys!

brad richards, on July 23rd, 2010 at 9:38 am

YEAH , it worked with 1 hard-reset thanks you

Vincent Naud, on July 25th, 2010 at 11:12 am

I wonder how many people saying “yay it fixed my problem” are still happy a few days later. I’ve tried resets, even a full restore on my 3G and it seems to fix the problem until a few days later when things slow to a crawl again. It must be memory leaks causing the phone to slow down and start having problems.

Sometimes loading the iPod app gives me a white screen for 10-15 seconds. Its random and hard to reproduce but it keeps doing it. Safari crashes all the time.

I only bought my 3G in Sept 2009 when it was the current model, my staff discount wouldn’t allow me a 3GS. I was happy with it till the iOS4 upgrade ruined my phone.

SpaceAce, on July 26th, 2010 at 6:23 am

Glad I stumbled across this — it worked well on my 3G just now. I’ll keep an eye on it to see if it returns to its former snail-like ways.
Thanks very much from a (hopefully) satisfied Aussie.

Kim Austin, on July 26th, 2010 at 11:34 pm

Yes, mine improved a lot, but I need to repeat the medicine every week or two, in order to kept my 3G with 4.01 fast.

Juan I. Cahis, on July 28th, 2010 at 6:35 pm

I am also voting this in as a temporary/time-limited fix…the first mumbo-jumbo comment made me smile as I somewhat agree…

I’ve experienced sluggish performance on my 3G as well after the iOS4 ‘upgrade’ and have tried all sorts of things to remedy – including the latest ‘turn of all categories in Spotlight search’ to see if it made any difference…and nothing has given me noticeable (read: acceptable) performance improvements…

What DID help out perfectly, was the downgrade to stock 3.1.3 again – now that is a viable solution, which will last…

Claus, on July 29th, 2010 at 2:30 am

One hard reset did the trick. Very much appreciated.

Brian, on July 29th, 2010 at 1:59 pm

first i did hard-reset
and now i always start XSysInfo app that clears memory and my 3g now works like when there was iOS 3.1.3

resetter, on July 29th, 2010 at 2:32 pm

In addition to the Double Reset. I’ve also found that removing all the options for Spotlight Search has additionally sped up the performance of my iPhone 3G.

Steve WilsonSteve Wilson, on July 29th, 2010 at 10:09 pm

I had horrible performance issues with my 3G after upgrading to 4.0 and then to 4.0.1. I found a tip which worked wonders for me:

1. Turn off Spotlight Search: Go to Settings | General | Home Button | Spotlight Search, and uncheck everything
2. Reboot your iPhone 3G: Just a normal power down and restart
3. Turn Spotlight Search back on: Go back to same screen as step 1, and re-check everything you unchecked in Step 1

You can more read about it on my blog:
http://www.davekawalec.com/2010/07/3-steps-to-fix-iphone-3g-slowness-after-ios4-upgrade/

Dave Kawalec, on August 1st, 2010 at 11:11 am

Everyone should try turning off the spotlight search. Go to settings, general, home button, spotlight search, and uncheck everything….I swear this helps. I was super upset after the upgrade and now I am much happier!!

Cowgirl, on August 2nd, 2010 at 2:10 pm

double hard reset all the way. what does it mean?

I have the iPOD touch 32 GB 3rd generation unit. It just got updated with the 4.0 OS and all of the sudden the integration with car menu system has slowed down by about 200%. I have 204 Albums on the unit and it was taking approximately 15 -30 seconds to load. Now it takes 2 minutes. I will try the hard reset and wallpaper disable and report back if it works. This is a very helpful post!

Just to add to the “me too” theme, I’ve been cursing my iPhone’s sluggishness for the last few weeks since I upgraded — I would never have bought a phone that was so slow to respond to input.

However, the double reset method above has given a decent improvement. Still not sure it’s *quite* as fast as it was before, but it’s certainly a vast improvement.

PS Not actually sure whether it needed two resets or whether the problem was solved after the first, but the second didn’t do any harm, and I’m happy with the result.

Hi,

It works unless you haven’t jailbroken your iphone 3g using redsn0w with an enabled option “enable multitasking”. iPhone 3G isn’t recommended to run iOS4.0 with multi-tasking option. although after 2 hard-resets, you’ll still feel the pain.

I have heard many a good response after performing the Double Hard Reset however, I am currently using an iPhone 3G on T-Mobile (it is unlocked,) and I was just curious if performing these “magical” resets is going to re-lock up my iPhone to AT&T.
Thanks in advance for the advice!

Worked for me. Not Like a 3gs or 4, but it solved some of my speed issues. Thanks.

I have the 3gs and updated to os 4 with loads of problems. Sending sms are so slow and I am not receiving calls when my phone is even switcheded on. All my contacts are gone.
I’ve restored the phone to factory settings and restored it as a new device but i want to know when doing this does should it go back to it’s original os setting of 3xxx. I still have os 4.0.1. after the restore. Is this right? I don’t want it.
Apple fix the os4xx. 3gs was so much better on previous os 3 software.
Thanks
Emy.

I’m going to double reset my iPhone 3G every hour until I can save up enough money to buy the iPhone 4 with the bad reception.

Worked for me to! Apps don’t crash anymore, open much faster, the ipod still opens slowly, though.

Thanks for the tip

Worked for me too! It DOES take a 2nd reboot. I also have verbose boot up (via jailbreak) and I can confirm that the 2nd time -not the 1st- it did do a diagnostic on my “hard drive”, and sure enough, it found (and fixed) a ton of problems. My phone, without a doubt, is much faster than before.

ADDITIONAL TIP:

Turn OFF spotlight on things you don’t need searched! (To do this, open Settings then General/Home Button/Spotlight Search – and uncheck what you don’t want–Keep in mind that Mail and Messages have their own search built in (you need to pull the screen down to see it), so you do not need them included in spotlight.

warren, on August 15th, 2010 at 11:37 am

OK i have to downgrade back to 3.1.2 is there a easiest way….redsnow or something else similar?????
1.Once a time i was jailbreak with redsnow installing multitasking and wall pp can i do this again but without all these functions???
IF i clean all ios4.0.2 with pressing the button clear all data and settings can i install the fresh copy of 3.1.2 via iTunes without pain and then jailbreak it again with redsnow or blackrain?????
Thank you to all of you and please for your answer i need IT!!!!!!

the true is the 3g iphone does not support multitasking option so, we need to disable it, there’s an app on cydia that disable multitaskind and wallpaper also the batery percentage make the iphone 3g usin ios4 work slow too.

i already do on my 3g iphone and it work perfect.

My iPod touch has been having lots of video issues. It was freezing up constantly. I did the double hard reset and it’s working great now! Thanks!

Jessica, on August 20th, 2010 at 11:17 pm

Wow – i tried this and I am surprised but glad to say that it actually works!
Weird.

Calle, on August 22nd, 2010 at 2:11 pm

It seems to help, thanks for advise!

kt, on August 23rd, 2010 at 5:31 am

It actually works. Opening a new SMS has gone from >10 secs to <2 secs.
Still filthy on Apple for pushing this out to 3G users and ignoring the issue.
Been a big fan in the past, but I'm not sure if my next phone will have an Apple logo on it now….

Neuse, on August 24th, 2010 at 5:55 pm

after upgrading to ios4 on my iphone 3g, my battery drains very fast, i thick its caused by background wallpaper or something else, i found that the status bar have no icon showing such as ringtone silent, missed call and new sms…, many cydia apps not compatible, crashed when launching, so i downgraded to firmware 3.1.2, now everything running good and smooth like before.

kelmen, on August 25th, 2010 at 9:02 pm

hi poller….
you can downgrade 4.0.2 to 3.1.2 it complicated littlebit but possible..
you must have shsh files stored in cydia… download 3.1.2 firmware save it to desktop .. connect ur iphoen via USB and open up itunes. then at the same time
press Shift key on you Keyboard your computer keyboard and mouse left click on restore it will ask you to browse IPSW then you should select 3.1..2 that you downloaded and restore it thats it.. enjoy anyproblem letme know

shah, on August 26th, 2010 at 2:56 am

this isn’t a permanent fix, ram will get clogged again in a while and the 3G will return to it’s sluggish self, imo the only permanent fix is going back to 3.1.3 or well..buying the iphone 4 or even 3GS.

Vishu, on August 30th, 2010 at 9:37 am

I’ve gone from loving my phone to cursing it. They should at least have the decency to acknowledge the problem and offer a simple downgrade of firmware. Until I read it here I hadn’t realized it was possible, I’ve been wishing I could go back since I put the new ios4 on. Thanks for that at least……..

Ryan montelione, on August 31st, 2010 at 1:55 pm

HEY i think i got it, i did everything people say here including triple reset with no luck, however i notice if you use gmail now you not only checking mail but also notes and calendar, i turned them off and left the mail option only and now my iphone it’s back to normal.

Cheers
