The 1.1.2 Challenge

A new 1.1.2 unlock challenge was setup by shaiss @ ModMyiFone to speed up efforts in breaking the pesky 4.6 bootloader found on current iPhones. The first person to provide ample proof of a 1.1.2 unlock will stand to win a small sum of money. The bounty currently stands at $20 but will increase as more donations are received.

To collect the prize, one must post a detailed software based unlock guide with screenshots before anyone else. Any unlocking software used for the unlock must be available for both Windows and OSX as well as its source code. Reverting the bootloader to an older version is also disallowed.

Geohot announces new bootloader exploits

Geohot has uncovered not one but two exploits for the 4.6 bootloader! Although the first one is a hardware exploit, any exploits that are found at this point could turn out to be useful in the future. The second exploit is software based, which could lead us closer to a new unlock, but it would require some smarty pants to figure out how to spoof the necessary bits. Maybe the bounty above will spur Geohot or other aspiring hackers to take a crash course in RSA encryption schemes.
