So I should receieve my iPhone 3GS on Friday. My hope is to be able to give my current iPhone 3G to a friend who also has AT&T. However, my friend does not need nor want the data package and solely wants the phone for the iPhone/iPod/Gaming/Wireless abilities. I was originally under the impression that I could Jailbreak the phone and simply place his sim card in the phone and it would work without the data package and obviously won't have internet access unless connected to a wireless netowrk. However, the more I read the more confused I become. I don't believe I need the phone to work on multiple GSM's? rahter just work without the data package with the same carrier in the US (AT&T). I was hoping someone could give me some advice, if this was possible, and if so which program(s) I would need and then I could research thoes more specifically. Currently, the phone has software 2.2.1 installed and I own a Mac, which the phone would be unlocked/synced with. Thanks!
