Background Information

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

• iPhone 3GS
• iPhone 4
• iPod touch 2G (old bootrom)
• iPod touch 2G (new bootrom)
• iPod touch 3G
• iPod touch 4G
• iPad
• Any other iOS device released thus far (though support for the AppleTV is negligible and hasn't been clarified)

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 a bootrom exploit (different to the greenpois0n one) to achieve the tethered jailbreak and unsigned code execution
• This also uses the same userland exploit discovered independently by comex
• Chronic Dev knows about this exploit and has confirmed its legitimacy

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 is probably only being released to pressure chronic dev into using the exploit in greenpois0n. [4] Geohot used a similar tactic to pressure the iPhone Dev Team into releasing a 2.0 jailbreak.
• The Chronic Dev Team are working extremely hard to implement geohot's limera1n exploit before the greenpois0n release date, though it will probably not use that exploit because timing is tight.
