Apple patched Geohot’s Limera1n exploit on iPad 2. iPhone developer and hacker iH8sn0w has confirmed it. For those who are not aware of Limera1n Exploit, is a bootrom tethered exploit which was make by Geohot aka George Hotz and used in Limera1n Jailbreak Tool to jailbreak iOS 4.1. Later Limera1n exploit was used in GreenPois0n, PwnageTool, RedSn0w and Sn0wbreeze.
Here’s what iH8Sn0w has tweeted:
From his tweet:
Confirmed: limera1n is patched in iPad 2.
Muscle Nerd from the iPhone Dev Team also confirmed the SHAtter exploit has been closed by Apple as well. This was discovered as MuscleNerd found the iPad 2 running a bootrom version iBoot-838.3 as compared to iBoot-574.4 found in the first generation iPad.
From his tweet:
iPad2 bootrom version iBoot-838.3 means it was compiled March’10. Seems geohot guessed right: limera1n was already closed
Early testing also seems to show at least one thing SHAtter depends on was gone by March 2010 too 🙁
This means any early iPad2 jailbreaks will have to be purely userland
@fr0st SHAtter can’t work at all with the “thing” I referred to gone
@hooners96 right. I guess this is a bit of a win for Apple engineers…they fixed both holes long before either exploit was developed.
As this is a bootrom exploit, the only way Apple could patch this exploit is by patching it on the hardware. That means, it can’t be patched via software update / firmware update. So, all current iOS devices expect iPad 2 can be jailbroken using this Limera1n exploit – Keep in mind that its a tethered exploit. That means you get a tethered Jailbreak for future iOS version and for all iOS device (except iPad 2) unless, someone like @comex provides a hack to change this tethered jailbreak to untethered jailbreak.
