Just a quick heads-up! The latest tweet from iOS hacker Comex suggests that new bootrom vulnerability has already been discovered and exploited by someone (was he able to Jailbreak iPad 2 on new Bootrom iBoot-838.3?) . However, there is no concrete proof that substantiates his statement.
@comex is your new iPad 2 exploit in the boot rom? Or a userland exploit? Kinda curious. I am one of the lucky ones who landed one day one.@Hoosiermo Userland, but I hear someone has a bootrom vulnerability that they might have exploited.
Those who don’t know, unlike JailbreakMe, Bootrom exploit is a low level-bootrom exploit, that can’t be fixed by Apple without a new hardware release of any iOS device. Just firmwares update will not going to patch the vulnerability. It also enable users to change boot and recovery mode logos among many other things.
Comex, who has already jailbroken his iPad 2 using userland exploit, is hard at work to package his exploit into a working jailbreak tool (JailbreakMe 3.0) for primetime usage. Interestingly, Stefan Esser is also busy in packaging his exploit to jailbreak iOS 4.3 firmware.
