Limera1n

Background Information

Limera1n is a jailbreak by geohot. It is presumed to be untethered on all supported devices, which include the following (but aren't necessarily limited to):

• iPhone 3GS
• iPhone 4
• iPod touch 2G (new bootrom)
• iPod touch 3G
• iPod touch 4G
• iPad

It has been demonstrated multiple times by geohot, using blog posts on his now private blog. Geohot showed off a high-res picture of Cydia on an iPhone 4. [1] He displayed an untethered jailbreak that met MuscleNerd's requirements for a good video on the iPod touch 3G. [2] In addition, he demonstrated Cydia, blackra1n, and a verbose boot on an iPad (before Spirit was released). [3]

Technical Information

• This does not use SHAtter.
• This uses at least one bootrom-level exploit and at least one firmware-based exploit (e.g. LLB, iBoot, Kernel) like the initial release of greenpois0n.
• Chronic Dev knows about this exploit.

Controversy

The timing impact of this jailbreak release will have major negative consequences on everyone, especially since this jailbreak IS patchable. If this jailbreak is released, the holes used in it might be needlessly burned, seeing as how greenpois0n is expected to be released the day before limera1n.

• Limera1n will reportedly not affect greenpois0n's release. [4]
• Limera1n is probably only being released to pressure chronic dev into using the exploit in greenpois0n. [5]
