iOS 4.1 Boot ROM Vulnerability Could Enable Jailbreaking

“Yesterday’s release of iOS 4.1 was good news for iPhone gamers and iPhone 3G owners who had performance issues post-4.0, but bad news for jailbreakers, with the Dev Team themselves warning users not to upgrade to 4.1 as there was no known way to reverse the baseband post-update. As usual, though, what’s true in the cat-and-mouse jailbreaking scene one day is not true the other, and now there’s good news for jailbreakers, at least in theory. iPhone hacker pod2g has revealed on Twitter that he has successfully discovered a new bootrom exploit, and even better: all the new iOS hardware including the iPhone 4 and new iPod Touch is vulnerable to it.”
