How to JAILBREAK iOS 4.1 on iPhone 4 & 3GS, iPod touch 3rd and 4th gen, and iPad using limera1n

This will guide you in using limera1n (limerain) to hactivate and jailbreak the following iDevices:

  • iPhone 4
  • iPhone 3GS
  • iPod touch 4th generation (4G)
  • iPod touch 3rd generation (3G)
  • iPad
Notice that these iDevices are relatively new which means that this jailbreak tool will NOT be compatible with older iDevices such as the iPhone 3G. You can use redsn0w on jailbreaking those older iDevices and you can read the guide for that by clicking HERE. DON'T ever attempt to use limera1n if you do not see your iDevice on the list above.

WARNING for iPhone users: If your iPhone is currently unlocked/jailbroken on a lower iOS (e.g. 4.0.2, 4.0 or 3.1.2), DO NOT update to 4.1 yet. There's NO unlock available for baseband 05.14.02 / 02.10.04 that came with the 4.1 update. Although limera1n can hactivate your iPhone, it will not unlock the said basebands.

Good news for iPhone 4 users, you can update to iOS 4.1 while keeping your baseband to 01.59.00. CLICK HERE to read the guide for that. Unfortunately, that process of updating will not work for iPhone 3GS.

Please take note of the above warnings before trying this out.

To begin, download limera1n. Make sure you have the final/official version of limera1n and NOT the beta releases. Use the ff links::

This process is 100% safe. It could also be because you didn't looked at the 2nd page of the homescreen yet. Usually, limera1n icon appears on the 2nd page. Siimply swipe (on the screen) from right to left to see it.
