Looks like Apple is on the lookout for all those mischief makers finding exploits in iPhone to unlock and jailbreak the new firmware 3.1.3. The latest victim is Sherif Hashim, the guy who enabled unlocking on baseband 05.12.01 for those who upgraded to the latest firmware 3.1.3. Looks like he and the guy behind sn0wbreeze and ih8sn0w also got banned from tyhe iTunes App Store.
