How To Jailbreak Your iPhone 4, iPhone 3GS Or iPod Touch… The Right Way



After months of waiting, Comex and the iPhone Dev Team have finally released JailbreakMe v3, allowing any iOS device running iOS 4.3.3 to be jailbroken just by visiting a simple web page.

Even though this is as simple as jailbreaks get, though, there’s still stuff that can go wrong, so we’ve put together this handy guide for any would-be jailbreakers. Here’s how to jailbreak your iPhone or iPod Touch… the right way.

Step 1 — Use Tiny Umbrella To Save Your SHSH Blobs

TinyUmbrella is a software app for your PC or Mac that allows you to save your iOS device’s SHSH blobs. Why is that useful? Because if you ever mistakenly update your jailbroken device through iTunes, your stored SHSH blobs will allow you to restore it to a past, jailbreakable version.

Download Tiny Umbrella here. Install it, open the program, highlight your iPhone or iPod Touch in the drop down menu to the left and then click “Save SHSH.” All done!

Step 2 — Make Sure Your Device Is Jailbreakable

JailbreakMe v3 exploits a PDF vulnerability that is present in multiple versions of iOS on the iPhone 3GS, both the Verizon and CDMA iPhone 4, the third and fourth-gen iPod Touch and both iPads (to jailbreak them, see our separate guide here). No other iOS Devices are supported.

To jailbreak your iPhone or iPod Touch, you need to be running one of these versions of iOS.

iPhone3GS: 4.3 through 4.3.3
iPhone4: 4.3 through 4.3.3
iPhone4-CDMA: 4.2.6 through 4.2.8
iPod touch 3g: 4.3, 4.3.2, 4.3.3
iPod touch 4g: 4.3 through 4.3.3

The easiest way as of writing to make sure your iPhone or iPod Touch is jailbreakable with JailbreakMe v3 is to upgrade to the latest version of iOS available for your iPhone or iPod Touch. Just plug your device into iTunes, click on it under Devices in the sidebar, then click “Check For Update” on the Summary tab. If your device isn’t up to date, you’ll be prompted to install the latest update. Do so… and prepare for jailbreak!

Step 3 — Back Up Your Device

Just to be on the safe side, back up your device under iTunes. Just right click your iPhone or iPod Touch in the Devices sidebar under iTunes and select Back Up from the contextual menu.

Step 4 — Open JailbreakMe on Mobile Safari

On your device, open MobileSafari and go to You should see something like this:

All you need to do now is tap the “Free” button once so that it turns into an “Install” button, then tap the Install button again. You should be whisked away to your iPhone or iPod Touch’s home screen, where you should see Cydia installing…

Once Cydia’s done installing, open it up and click “User.”

You should see Cydia’s main homescreen now. It’ll look like this.

Congratulations, you’ve successfully jailbroken your device! But there’s just one more step.

Step 5 — Secure Your Jailbroken Device

JailbreakMe v3 uses a PDF exploit to jailbreak your iPhone or iPod Touch, just like the previous versions. The only problem? While Comex has used that PDF exploit to do something good for your device, other hackers can use it to invisibly compromise your system… and now that the jailbreak is out, they’ll know exactly how.

Luckily, now that your iPhone or iPod Touch is jailbroken, it’s easy enough to patch that PDF Exploit. Load up Cydia to download PDF Patcher 2.

If you haven’t run Cydia before, it’ll ask you what sort of packages you want to see. Just tap “User” and wait for Cydia to download all the packages it needs. Then do a search for “PDF Patcher 2,” tap the search result and click the Install button at the top right. A new window will pop up asking you to confirm. Once that’s done, PDF Patcher 2 will install and Springboard will restart.

Now whenever a web site tries to open a PDF on your device, you’ll be alerted and asked if you really want to continue.

Congratulations! Your iPhone or iPod Touch is now jailbroken and secured against further PDF exploits! Let us know how it’s working out for you in the comments!

    But iphone 4 still can’t be unlocked. :-(

    Waaaay too much hassle, considering it doesn’t give you any advantage anyway.    

    If there was some reason you *needed* to jailbreak then maybe, but with the current state of affairs it just isn’t worth it IMO.  I got enough stuff to worry about without having to manage the software revisions and instals on my phone.  

  • prof_peabody

    iPhone 4 has been sold unlocked in many countries for years.  I personally have never bought a locked iPhone, and I’ve owned all the models except the first one which wasn’t available in my country anyway.  

    Also, the USA just (finally!) got unlocked iPhone 4’s a month ago.  

  • Brady Kenniston

    So I hit the install button on my Verizon iPhone and Jailbreakme 3.0 installed Cydia. Is that a good thing?

  • Figurative

    Is it me or is there an overabunedance of “jailbreaking” stores on C.O.M.?

  • appledrunk

    There is no “hassle” in this jailbreak, it’s as easy as it can get. The author simply mentions using TinyUmbrella to be sure you can revert back to 4.3.3 in the future. Though I do believe Cydia will save your SHSH blobs when you launch it anyway.

  • Alek Popov

    Yes it can. Just use the Gevey Turbo SIM.

  • Apple Hardcore

    Awesome stuff. JailbreakMe is as easy as it gets.

  • Tim Pease

    I have no idea why no one brings up this point, but it is absolutely ESSENTIAL to change your root password when jailbreaking an iDevice.  There are many tutorials out there explaining how to do so.    Once an iDevice is jailbroken, it is very easy for a hacker to use Apple’s default password (alpine) and gain access to the device.

  • Noella Licandro

    That’s interesting considering apple just made their beta program open to the public.

    I am in the UK, and i have got my phone unlocked by orange so i can use my o2 sim. would this jailbreak stop me from using my o2? I ask as last time i JB’d using Pwnage tool & was unable to use my o2!

  • Atikur Rahman

    no one knows???

  • Wes

    the hell you got a link sending people to download some crap?! Please delete her comment! I closed the webpage before it could start downloading anything….idk if it’s safe but don’t take the chance!

  • habibmustafa

    I recommend iSHSH from Cydia store (it’s free). Not only it backs your SHSH blob to Cydia, but you can also send it via e-mail for personal back-up.

  • Fred Maxwell

    It’s you.

  • Fred Maxwell

    So being able to set up my unlimited plan iPad as a 3G hotspot is not an advantage.  Thanks for letting me know about that, professor.

  • Stephen Zarcone

    if i restore my iPhone to factory settings will it not be jailbroken anymore?
