Jailbreak for iOS 4.1 is available now, you can use Limera1n to jailbreak iOS 4.1 on iPhone 4, iPhone 3GS, iPod Touch 3G, iPod Touch 4G. Limera1n jailbreak is available for Windows and Mac. Lets see how to Jailbreak iOS 4.1.


  • I recommend you to read all steps first and understand them (if you don’t understand anything write a comment below).
  • Restore iOS 4.1 firmware on your iPhone or iPod Touch device. iPod Touch user don’t need to worry, if you are iPhone user and depend on unlock then don’t update iPhone to iOS 4.1 firmware, because this iOS 4.1 update will upgrade your iPhone baseband and at the moment Ultrasn0w doesn’t support lastest baseband unlock.
  • However, iPhone 4 users can upgrade iPhone 4 to iOS 4.1 without upgrading the baseband and then jailbreak and unlock iPhone 4 with UltraSn0w.

First you need to update your iDevice to iOS 4.1 firmware, do it according to your device.

  • iPhone 4 users follow this link to update iPhone 4 to iOS 4.1 firmware without upgrading baseband (then come back here to step-2).
