History of iPhone
On October 16, 2007, the iPhone Dev Team released AnySIM 1.1, the free utility that unlocks iPhones. The updated version works on firmware version 1.1.1, but doesn't fix baseband problems caused by updating an unlocked 1.0.2 phone up to 1.1.1. On October 23, 2007, the iPhone Elite Dev-Team released Revirginizing Tool to rebuild the lock table in the seczone area to repair the damage done by the original anySIM 1.0x unlockers so unlocked 1.0.2 iPhones can upgrade to 1.1.1 without bricking iPhone. The tool is unbricking the previously bricked iPhones.
