How-To: Complete Guide to Unlocking and Jailbreaking the iPhone and iPod Touch
11:59 pm, September 27th, 2009, Tim Cox
Unlocking your iPhone used to require a soldering iron and some kid from New Jersey. Now all you need to make your phone work on carriers other than AT&T is Cydia and ultrasn0w.
Preparation for Unlocking the iPhone
Open up Cydia.app and hit the search button at the bottom right corner of your screen.
Type in “ultrasn0w.” Note the “o” is actually a zero. You’ll be presented with these search results:
Select the bottom option. Cydia then presents you with information about the app along with an install button on the top right. Hit the install button.
Finally, the confirmation screen let’s you know exactly what packages Cydia will be installing on your iPhone. Hit the confirm button.
Cydia will now download and install the software unlock on your iPhone. When finished, you’ll be presented with “Reboot Device” button.
Once your iPhone reboots you’ll have an unlocked device, which you can apparently sell on eBay and pay off some college loans. To use your phone on a different carrier, just swap out the SIM card and enjoy feeling what freedom feels like.
To maintain this software unlock, no matter how attractive the software upgrade might be, you should only upgrade your phone to the latest Apple iPhone firmware when Dev-Team tells you it’s safe.

I have an Iphone 3G with 3.1 software. I unlocked it using the same instructions above
However, the phone is still searching for a signal. Is the Ultrasn0w not ready for 3.1?

@Radesh = Ultrasn0w will not be able to unlock on 3.1. Check the Dev Team blog for more details.

wow, there’s some balls. lets post information that might actually be illegal to disseminate but then really get ballsy and not post a warning that using said information voids all warranties so if the phone ends up hosed Apple will basically tell you to piss off. I would think CoM would want that warning if only to cover their own butts.

Please… go ahead and jailbreak. Its your warranty and life.
But stop trying to form the impression that the percentage of users who are ‘outraged’ over Apple’s ‘fascist’ policies towards apps is any more than a handful of bored basement jockeys.

As for fretting about what Apple will or will not do, warranty-wize, one can always restore the firmware. No one will be able to tell that your device was at any time jailbroken. Whether jailbreaking is illegal or not hasn’t been decided yet. It is YOUR device — that much is certain. Can you mod your car? Paint your house a different color? Can you burn a book you just bought?

Got an old iPhone for the camera… no sim card… won’t do anything but let me dial an emergency call…. anyone know how to bypass this? I just want(ed) an iTouch with a camera.
Thanks

I disagree with some of the comments above. If you have a 3GS and use 3.1, you cannot “always restore the firmware”. apple is no longer signing signatures for 3.0 or 3.0.1 making downgrading to them almost impossible. If I am wrong please (gently) correct me…
The Digital Alchemist, on September 28th, 2009 at 7:23 pm
Steven, you are going to have to have a sim card in the slot or it won’t ever get past that screen. it can be a dead sim but it has to have something. and if you update the firmware it will have to have that sim back in the slot for the update.

I have a 1st gen iPhone. It was jailbreaked on version 2.1, but my wife connected the iphone to the computer on usb to recharge and clicked yes to upgrade to version 3.1
Now, as you expect the fone boots up but only allow us to make emercengy calls (screen shows that connect to itunes image), it does recognize the rogers sim, but i can’t do anything but emergrncy calls. I’ve tried to jailbreak it again w/o success. I put it on DFU mode but always get error 1600.
Any ideas ? Thanks in advance to you all.

So how do I downgrade my 2nd gen ipod touch to 3.0 or 3.0.1?
Doug, on October 9th, 2009 at 7:13 pm
Could someone tell me why the whole world of pain to actually do this, as well as risking bricking your phone, is worth it. Is an unlocked iPhone ‘that’ good ?
joe, on October 16th, 2009 at 11:01 am
The article was useless. I downloaded the pwnage tool and the firmware file. The tool could not find the file and when I browsed to the file I could not select it at first. When I finally did select it, I got an error message saying it was the wrong file. Waste of time.

Im thinking about to jailbreak my ipod touch but im a little scared… I saw a video on youtube about a guys who has jailbroked hes ipod and it was f*cked up… Just wanna be sure that it wont completely smash my ipod if i jail break it..

I held out as long as possible before getting the new Iphone 3Gs. Mostly becasue of At&t’s very over priced service. For a decent plan it will cost you 165.00 per month. How is it that Sprint can charge 99.00 for unlimited? Ok I’ll change the cost issue for a min. If you pay for unlimited web access why do they want to charge extra if you tether to your phone from a laptop? Right there is reason enough to jail break your phone you will save enough over 1 year to buy the phone outright. Most of the Apps on the Itunes App Store are for children!!! There are a few good ones that adults can use but you have to pay for them and most have an additional monthly charge. Still not convinced, Turn your Iphone into a wireless router access point, imagine what you can do with that if you travel alot liek I do. No more hotel fees, for internet, not paying for hot spots at coffee shops and airports. Yes there is a danger of bricking you Iphone, but if your carefull and know what your doing the savings are definitly worth the efforts. Why pay extra for a feature your phone already has. Apple should wake up and smell the millions of phones they could sell if they left the phones unlocked. It will happen as soon Apple needs market share. This is all you need:

I wish I knew this before I switched from Verizon they have much better coverage cost is all most the same but the service is much better.
-Cheers you now have a choice
