Now that iPad 2 in out and hackers have already started testing bootrom exploits like SHAtter and Limera1n on iPad 2. Early results from this testing are not in favor of the jailbreak community because both the SHAtter and Limera1n exploits are said to be patched in iPad 2.
If you don’t know, Bootrom exploit, SHATTER and Limerra1n exploit for instance, is a hardware level exploit and can only be patched with hardware revision. All the recent jailbreak tools like Greepois0n, RedSn0w use Limera1n exploit to jailbreak iPhone, iPad and iPod Touch. Geohot released Limera1n jailbreak back in October last year that forced the Chronic Dev Team to save their SHAtter exploit to for future iDevices like iPad 2 and iPhone 5.
Early testing shows that the iPad 2 has a new bootrom with patched Limera1n and SHAtter exploits. Both the exploits seems to be patched since March 2010, long before they were found by Geohot and Chronic Dev Team.
MuscleNerd: iPad2 bootrom version iBoot-838.3 means it was compiled March’10. Seems geohot guessed right: limera1n was already closed
MuscleNerd: Early testing also seems to show at least one thing SHAtter depends on was gone by March 2010 too 🙁
MuscleNerd: This means any early iPad2 jailbreaks will have to be purely userland
This leaves us with no bootrom exploit, atleast for now. All the current iDevices except iPad 2 are still vulnerable to SHAtter and Limera1n because there’s no hardware revision for those devices out yet.
With GeoHot busy in dealing with Sony Lawsuit, we hope Dev-Team, Chronic Dev-Team, Pod2g (SHAtter founder) will bring us a new bootrom exploit and/or Comex (the userland jailbreak expert) comes up with JailbreakMe update to jailbreak iOS 4.3 on iPad 2. Unfortunately, Comex has this to say:
Comex: I must be really unlucky… I just realized that my best kernel bug was closed in iOS 4.3.
On side note, an iPhone hacker named i0n1c has already achieved the iOS 4.3 jailbreak untethered. We’ll update you as we know more about the ipad 2 jailbreak. Stay Tuned!
