Just bought a iPhone 3G 8GB, is there anything I need to do to it once I get it in the mail.
You will need to jailbreak it then unlock it with ultrasnow. It all depends on what firmware and baseband (modem firmware) version it's on which way to do it...
If it's jailbroken and unlocked do you know if you can use it without a data plan but just use it with wifi?
