SHAtter, Limera1n Exploit Patched in iPad 2

With Apple’s release of the iPad 2, some of the exploits used to create jailbreak tools for iOS have been patched. According to Canadian iPhone hacker iH8sn0w, the Limera1n exploit has been closed:

Muscle Nerd from the iPhone Dev Team also confirmed the SHAtter exploit has been closed by Apple as well. SHAtter was an exploit that the Chronic Dev Team discovered, and but was saved last minute as Geohot released Limera1n to the public.

Looks like Apple has the upper hand right now in the jailbreak cat and mouse game right now. However, I wouldn’t count out any of these Dev Teams. One man does have an untethered iOS 4.3 jailbreak, and that’s Stefan Esser aka @i0n1c. Is he our only hope right now?

Update 1: Stefan clarified his stance with his jailbreak via his YouTube channel (thanks Wsmithitguy):

Good morning.

This video demonstrates my iPad 1 running untethered jailbroken iOS 4.3

The jailbreak uses a *UNDISCLOSED* exploit in the iOS Kernel. Installation is similar to previous iOS versions which means you require a bootrom exploit (or something else) to install it in the root partition.

Because there is no public bootrom exploit for the iPad 2 at the moment it will not work for now.

However the jailbreak can be made compatible with all devices that are vulnerable to the limer4in exploit and that are supported by iOS 4.3

Because of several changes in iOS 4.3 in comparison to iOS 4.2.1 the jailbreak is NOT READY yet. That is what the *ALPHA* means. I need some time to check what kernel patches are actually required to work 100%ly.

However I recommend the dev-team or chronic-dev to first release a *tethered* iOS 4.3 so that everyone can test if their nice feature actually work. I guess most people require Mobile Substrate to work and AFAIK it does not work due to ASLR. It would be a waste if Apple kills an untethered jailbreak before Mobile Substrate works.

That said I will release the jailbreak when a) there is no other untether by the time I am finished b) if MobileSubstrate works.

Any report that I wait for iOS 4.3.1 is just a misinterpretation of my words.
I merely think that Apple should release a iOS 4.3.1 soon, because it is in their interest to not wait for several months when everyone knows that there is a remote exploit in MobileSafari that might have leaked during the #PWN2OWN contest.

Check back in the next days for more information about when and where you can get it.

DO NOT LET YOURSELF GET SCAMMED BY ALL THE OTHERS TRYING TO SELL YOU THIS EXPLOIT. IT WILL NOT LEAVE MY HOUSE BEFORE IT IS FINISHED.

    BTW: I never said that I would wait for 4.3.1 to be released. I only said that releasing it now might burn it fast.
