The SHAtter exploit found by pod2g appears to have been leaked. Who leaked it and for what reason is still unclear. What is clear is that Apple will certainly find a way to patch the hardware if it did in fact leak. When Limera1n was released, it kept the SHAtter bootrom exploit safe for future jailbreaks as it would require a complete hardware revision to be done by Apple.
SHAtter basically used a hardware exploit in the A4 series of devices (iPhone 4, iPad, AppleTV 2nd generation, and iPod Touch 4G). You can bet Apple will make a hardware revision to patch SHAtter. It seems there is some drama between some members of the jailbreak community over who actually "leaked" the SHAtter exploit.
@P0isixninja of the Chronic Dev Team is pointing a blame finger to @Musclenerd. As Musclenerd concentrates on unlocks, it seems unreasonable to think he'd leak an exploit he would need in order to create an unlock. Click through for a response to the drama from @comex, who claims if it doesn't stop, he'll just e-mail the exploit directly to Apple. Not good news for the jailbreak community.
The part of Comex's tweet that got me was where he said (the real) SHAtter. Digging further into Twitter shows that maybe a fake exploit was leaked on purpose. We'll update when we know more.
What are you guys' thoughts? It's been a crazy evening for jailbreakers. First Comex stated the Christmas untethered deadline would be missed, and now a leaked exploit. Lend us your thoughts in the comments!
