NCK Length of iPhones

Geohot has discovered that the master unlock code (NCK) of the iPhone is . This key is unique to each iPhone and allows the iPhone to be permanently unlocked, which makes it very interesting as a long term unlock solution. Attempting a brute force attack (trying all possible combinations) on such a long key length is neither feasible nor practical, and as such, he hopes to identify similarities between these NCKs in order to cut down on the time required to look through the entire key space.

However, as the iPhone allows only 5 tries of the NCK, the only sane way to carry out a brute force is outside the iPhone environment. This was made possible recently with the . Other folks are now looking into retrieving NCK codes for iPhones with the 3.9 bootloader so that they can stay unlocked forever. No luck for iPhones on the 4.6 bootloader though, an update from Apple is still required for this method to succeed.
