Guide To Jailbreaking Your iPhone, iPod Touch, iPad [iOS 4.3.3]

Jailbreaking is a process that changes little by little with each iOS upgrade. Rather than always publishing new guides, we’re simply going to keep this one up to date. If you want to jailbreak your iOS device, you’ve come to the right page.

Current Untethered Version: iOS 4.3.3 For additional jailbreak options for other versions of iOS, please see the list at the bottom of this page. As this guide is updated, previous versions of the guide will be archived there as well.

Current Untethered Version: iOS 4.3.1 For additional jailbreak options for other versions of iOS, please see the list at the bottom of this page. As this guide is updated, previous versions of the guide will be archived there as well.

Not sure if you should jailbreak? We love jailbreaking our iDevices, but it’s not for everybody. If you’re not sure, you should read both our reasons not to jailbreak and why jailbreaking is awesome.

The video above will show you how the whole process works, both on your computer and your iOS device. The video depicts the jailbreak process for iOS 4.3.1 but it is identical to the process for iOS 4.3.3 (and 4.3.2, for that matter). Here are the individual steps:

  • Connect your iOS device to your computer. It’s always good to back it up before jailbreaking (use PKGBackup if you already have a jailbroken device and want a more comprehensive backup) in case something goes wrong, but before you get started with the jailbreak you’ll want to quit iTunes.
  • Download redsn0w from the iPhone Dev-Team, download the iOS 4.3.1 IPSW for your specific device, and the update to the latest version of iTunes. It is very important that you download the IPSW file that corresponds to your specific iDevice or this will not work.
  • Open the IPSW file with redsn0w and let redsn0w do it’s thing. When it’s done it’ll ask you to select some options before starting the jailbreak process. You’ll have four at the bottom of your screen and you really only need to select the first, which is “Install Cydia”. If you’re not familiar, Cydia is basically the jailbreak app store and you’ll need it to install jailbreak apps, hacks, extensions, etc.
  • On the next screen you’ll be asked to turn off your iDevice and connect it to your computer, so do that. Then get ready because as soon as you click next you’re going to have to do some quick work.
  • To start, hold down your power button for three seconds. After three seconds, don’t let go but start pressing your home button as well for another 10 seconds. After that 10 seconds has passed, let go of the power button but not the home button. Redsn0w will tell you to hold the home button for about 15 seconds but in most cases you’ll be able to let go a lot sooner than that. You’ll know because the instructions will disappear and stuff will start happening. Redsn0w will guide you through this process as it happens so don’t worry about getting the timing right. If you screw it up — and you probably will the first time — you can always try again.
  • Once you’re done you’ll see a lot of text appear on your iDevice’s screen. This is normal. Pretty quickly redsn0w will tell you it is done and you’ll just have to wait for things to finish up on the iOS screen. iOS will take several minutes to finish so be patient. Eventually your device will be ready and it’ll reboot all by itself.

And you’re done! You’ll find Cydia installed on your home screen (although if you have a ton of apps you’ll need to scroll through pages to find it). Launch it and you’re ready to go! Don’t know what to do next? Check out our jailbreaking tag page for some ideas.

Jailbreaking Options for Older iOS Devices


  • I’ve asked this before on Lifehacker but didn’t get an answer, I’ve got an iPhone 3GS on 3.1.3 jailbroken and working how I want it.

    Is it worth upgrading to 4.2.1 or just leaving it alone?

    • Well it is well worth the upgrade to ios 4.2.1 whilst u can update to it. What i would recommend is saving ur shsh (google how to do so) so if u do not want ios 4.2.1 u can downgrade back. What i would also recommend if before u upgrade makesure u download in cydia springback (this remembers your home screen layout) and aptbackup (which will download all your cydia installed packages after upgrading and remember there settings) youtube aptbackup for a tutorial. Once downloaded you should open it up and click the button backup until its complete. Then go in springback and click save then save all (this will remember ur homescreen layout) once both are done, connect ur iphone to your pc and in itunes right click on ur iphone in the devices tab and click backup, once complete and backedup click the update button and wait for your iphone to update, once complete and everything has sync back to ur iphone you want to right click ur iphone in the devices tab and click “restore from backup” and choose the backup you done not so long ago “it will have a time and date” once done download greenp0ison and follow the instructions to jailbreak, once jailbroken launch loader and install cydia, make sure that autolock in settings is put as never and then open cydia and download the changes. Once done and resprung , open cydia and redownload aptbackup, once its downloaded click the restore button and leave your iphone (its best connected to wifi) your iphone will take about 15 minutes so be patient, when done ur iphone will reboot and everything will be as it was, if ur apps are not in the same places open springback and choose then backup and hit restore all.
      Upgrading to ios 4.2.1 is a very essential upgrade as it has lots of new features and battery and performance. Aswell as ios 4 only apps. Do the steps i said if u want to update to any ios and keep your jailbreak stuff – make sure you allways save your shsh before updating so u can downgrade if the jailbreak isnt out yet – also make surw before updating a jailbreak is released which in this case it is, any help email me : [email protected]

    • Replying to myself, upgraded to 4.3.1. Few things better over 3.1.3, Safari has search, “personal hotspot” (tethering) built in, game center if you’re that way inclined, boots faster.

      Xander, it works, but there’s probably no reason to upgrade from 4.2.1, google for a changelog to find out.

  • I just received an Ipad Touch as a gift. Version says 4.2.1 and an MC ### model. How do I know if it is 2, 3 or 4 geneneration? Incidentally, when I boot, the Apple logo turns and becomes a skull just like the green poison logo. Does this mean that it is already jailbroken? Thanks for helping a noob…

  • has anyone had any proven success with this?

    i have a working 4.2.1 jailbreak and am unsure if i should bother upgrading then re-jailbreaking..

  • Pls help how to jailbreak my ipad 4.3..than,x…sorry im a noob..i have to update it to 4.3.3? Or what can you recommend..hanx..
