Unlock iPhone 3G With Yellowsn0w

The much awaited iPhone 3G has also been unlocked. The DevTeam has released yellowsn0w, the world's first iPhone 3G unlock. I’ve heard the software is automated and you can easily unlock the iPhone 3G with a fly. You must upgrade to the latest baseband 02.28 though in order to use it. It is possible to use it with the older baseband on firmware 02.27 but the DevTeam has exclusively restricted it to work with the newest baseband. So before trying it, upgrade to firmware 2.2 with the 02.28 baseband.
Thank not to God but to DevTeam that now, people aren’t bound to use AT&T.
