imminent launch of iOS 4.3.1, the site also offered unofficial release notes to highlight the changes brought by the update, including a fix for an unspecified “iPad 2 jailbreak vulnerability.” Once the update was released, the jailbreak community quickly realized that this unknown vulnerability was nothing more than an exploit found by iPhone hacker comex in all version of iOS from 4.0.2 to 4.3. And here is the kicker: somehow, Apple managed to discover and close the exploit before a jailbreak using it hit the streets. For the first time since the iPhone hit store shelves in 2007, Apple has managed to block a jailbreak method before it was released. The exploit fixed by Apple was a fairly undocumented exploit comex was keeping for an upcoming jailbreak, and while this could be nothing more than a coincidence, the jailbreak community is becoming increasingly suspicious about the fact that Apple might have connections with some of its members, allowing the company to patch security holes before they can be used to build jailbreak tools. In comex’s own words:
I try not to be paranoid, but it is really hard to explain this as anything but a leak.Whether comex’s exploit was fixed miraculously, or leaked by a community member, one thing is for sure: Apple is cracking down on jailbreaking, and instead of reacting, the company is now pro-actively fixing the security holes of its operating system, to prevent new jailbreaks to be released. Some good news for jailbreakers, though: a new exploit compatible with iOS 4.3.1 was recently uncovered, and the Dev Team is getting close to releasing an iOS 4.3 untethered jailbreak.
