After trying to update the 3g to the 3.1.2 software in itunes, an error message # 1002 occured saying that the iphone can not be restored and updated. I tried many more times using different computers and accounts. Always the same error. Then I tried to jailbrake it using blackra1n and the phone kicked into a gear. Everything works, except that I can't get any reception. I wanted to unlock it, but that's when I realized that the phone is running the 3.1.2 but with 02.28.00 baseband. Any suggestions how to fix this? Thanks
