I will be receiving a iphone 3g from a relative. I DON'T plan on using it as a phone at all. I understand it can be used an ipod, I have a few problems. I know that a iphone needs to be activated in itunes, the problem is I will not get the sim card with the phone and have been researching this a little bit and found out itunes wont let me use it unless activated. An att store is within walking distance, can I get a blank sim from them just so I can activate it in itunes? Anyway to use the iphone on my system so it syncs with my apps etc..,without a sim? Any help is appreciated.
