So Sorry for the wrong info above dude.

For the iPhone 2G, install firmware 3.1.2. Then use either spirit or blackra1n to jailbreak it. After that open cydia, let it load and run its cycles. then instead of ultrasn0w that i suggested above, Search for "BootNeuter ." Before you run the app though remove your SIM from the phone. Run bootneuter slide the Unlock option to ON, then press Flash. your baseband will get flashed and you should have an unlocked iPhone 2G.
