I had problems with my iPhone 3G Baseband 05.16 of the fact the GPS did not work. After I used your system everything is back affixed.
Now THIS is what I've been searching for. I needed to unlock this iPhone for use with a non-AT&T provider. Downloaded this system, downgrade , and now unlock . Highly recommended system. Wow!
Easy and fast. Very reliable. They Downgrade my iPhone 3GS in less than 2 hours. I'm very pleased with their service.
