Chronic Dev Team’s p0sixninja said, at jailbreaking convention MyGreatFest, that five exploits have been discovered for the A5 chip. Unfortunately, because the statement went out a bit too early, Apple managed to fix the critical ones. The iPhone 4S is equipped with it but so far jailbreak enthusiasts had to choose between a tethered jailbreak (that went away after every reboot) and a semi-tethered jailbreak that is situated somewhere in between the tethered and untethered one.
P0sixninja has been building up the buzz on its Twitter page for something coming soon on greenpois0n’s website and we were hoping for an untethered jailbreak for the iPhone 4S. That didn’t happen but the team made an interesting “behind the scenes” post.
Turns out Apple is finding out about exploits via its own system that is sending “crash reports” back to the mother ship. The team, in their efforts to find the jailbreak, are crashing certain applications but have disabled the option that allows for crash report sending on their devices. They came out with an application that “copies all the crash reports off your device (which, under normal circumstances, would be sent right back to Apple), and instead sends this data to a secure, private server hosted by your friendly Chronic Dev team”. The application also prevents iTunes from sending this information to Apple.
With this method, the team is looking forward to identifying vulnerabilities in applications by employing the same method Apple is using. If you want to support the effort, there’s a Mac version available for download (with a Windows client coming soon). If you’re interested in more details, hit up the source link.
