Apple closes PDF flaw in iOS updates for iPhone, iPad
Apple released iOS 4.0.2 for the iPhone and iPod touch, and iOS 3.2.2 for the iPad on Wednesday, effectively closing the PDF flaw which allowed hackers access to the internal code of those devices. The exploit was central to the jailbreakme.com hack released earlier this month. According to release notes with the updates, the PDF fix is the only change made to the code of the OS.
The jailbreak also made it possible for the iPhone Dev Team to release a version of its ultrasn0w carrier unlock for the iPhone 4 for the first time, which it did two days after the release of jailbreakme.com.
The Cupertino company said shortly after the jailbreak that it was aware of the issue and would be releasing a fix. It is not clear what the Dev Team's next move would be, considering anyone who updates would now be unable to use the site.
"Comex," the developer behind jailbreakme.com, only said as part of a tweet late Tuesday that "[I] guess I need to get working on the next jailbreak," likely in reference to the anticipation that Apple was about to update iOS, which it did indeed do.
Users wishing to update to the new software would be able to do so by connecting their iOS device to iTunes, and clicking "Check for Update." Similarly, those who may be in line for an automated weekly check for updates may start being prompted to upgrade beginning today.
It appears that those who have jailbroken before the fix would still remain jailbroken, although that has not yet been independently confirmed.
