Limera1n

Geohot has just released limera1n to jailbreak iOS 4.1 and iOS 3.2.2.

We had reported yesterday that he had discovered a new bootrom exploit and was planning to release a jailbreak tool called limera1n that made use of it soon.

Limera1n RC1 will jailbreak iPhone 3GS, iPhone 4iPad, the iPod Touch 3G  and the new iPod Touch 4G.

Geohot has posted the following details on his website:

limera1n, 6 months in the making

iPhone 3GS, iPod Touch 3G, iPad, iPhone 4, iPod Touch 4G
4.0-4.1 and beyond+++

limera1n is unpatchable untethered thanks to jailbreakme star comex

Geohot claims that he has released limera1n today a day before the release of greenpois0n by the Chronic Dev team because he wanted them “to do the right thing”.

He has currently released the limera1n RC1 for Windows users and is planning to release the Mac and Linux version shortly.

Please note that jailbreaking your iPhone may void your warranty and hence proceed with caution and at your own risk. Please don’t forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.

If you want to unlock your iPhone then do NOT use limera1n. Dev Team will be releasing PwnageTool that will preserve the baseband while updating the iPhone to iOS 4.1.

We hearing reports that it might not be properly tested so our advice would be to wait until we hear some positive feedback.

But if you're brave enough and willing to take the risk then you can download limera1n from this link.

Please don’t forget to let us know how it goes.

Update 1:

Geohot has just updated the post with the known bugs:

  • 3GS new bootrom is broken fix pending
  • some people need to restart to get the Cydia icon to show up after installing

Update 2:

Limera1n prompts you with some simple instructions to jailbreak your iDevice. After you have successfully jailbroken, search for the Limera1n app and install Cydia – the App store for jailbreak apps. After installing it, restart your iDevice.

If you have problem launching Limera1n app or Cydia doesn't up even after restarting then try jailbreaking again. 

Update 3:

Joshua Hill (aka p0sixninja) of the Chronic Dev team has tweeted that they will incorporate the exploit used by Geohot in limera1n in their jailbreaking tool – greenpois0n that they were planning to release tomorrow. They might not be able to release it 10:10:10 GMT tomorrow. But it means that they will preserve the SHAtter exploit for iOS 4.2.

Update 4:

iPhone 3GS (new bootrom) users should try using the latest version of limera1n as Geohot has fixed the issue in limera1n RC3. 

You should also be able to uninstall the limera1n app.

Update 5:

iPhone 3G and iPod Touch 2G users can use Redsn0w to jailbreak iOS 4.1.
