This just in (and it looks to be the “surprise” that pod2g talked about before): The new iPad (aka, iPad 3) will be Jailbroken on its arrival day. Stefan Esser, better known as i0n1c in the jailbreak community, has confirmed by tweeting – 5 more days until I will have a jailbroken “the new iPad”. This could mean that the hacker has working exploit in hand that will jailbreak A5X based “The New iPad” as soon as he receive the latest tablet in hand (on March 17th).
It all started in January when pod2g’s latest blog post hinted that i0n1c has discovered a new exploit in LC_SEGMENT64 and a way to authenticate the binary using loader and that we could see it in action in the 5.1 jailbreak. Details are thin whether it’s a bootrom or userland exploit but the tweet suggests that the exploit is full-blown and not just half-cooked untested vulnerability. In addition to jailbreak iPad 3 on iOS 5.1, the exploit could support jailbreaking A5-based iPhone 4S and iPad 2 too.

Fearing possible leak, i0n1c never divulged details about 5.1 untethered jailbreak exploit, but I can only expect that this release will be made public when the time is appropriate, maybe after successfully testing the vulnerability on latest iPad (if A5X don’t break the exploit, of course).
