Earlier this week it seemed as though an iPad 2 jailbreak wouldn't be too far off. This is because iOS 4.3 GM was easily jailbroken on previous devices
SHAtter, discovered by Chronic Dev Team's PosixNinja, made use of an A4 chip exploit, which meant that all future iOS devices would be jailbreakable as they ran on Apple's custom A4 processor. The SHAtter exploit never saw the public eye, because GeoHot released his jailbreak, which used his A4 chip exploit, Limera1n before the Chronic Dev-Team could get their jailbreak out. This caused a temporary feud, but all was forgiven by the next day.
Well, guess what? The iPad 2 is a hardware revision running on the A5 processor, and both of the aforementioned exploits have been patched by Apple.
iPhone Dev-Team's MuscleNerd recently Tweeted regarding the fix:
"Early testing aslo seems to show at least one thing SHAtter depends on was gone by March 2010 too :("
"SHAtter can't work at all with the "thing" i referred to gone"
"iPad2 bootrom version iBoot-838.3 means it was compiled March'10. Seems geohot guessed right: limera1n was already closed"
It's interesting to know that fixes were actually around a year ago, long before the hacks were even released.
For now, MuscleNerd says any early jailbreaks for the iPad 2 will be strictly userland, likely from a hacker like Comex.
Oh well, it's part of the constant cat and mouse game between Apple and the iOS hackers. Something will come around, it may just take a little bit longer than we initially expected.
