I tried to search this topic before I posted, but came up with no luck. But if you can point me in the right direction please do. Now to my question. I am currently on a AT&T family plan, with a Samsung, slide phone. I want to just buy a iPhone from Apple, or ebay or some sort, and just put my sim card in the iPhone. I realize without the iPhone plan some of the features may not work, but I don't care as long as I can use the phone and Ipod part, is this possible? Thank you a lot for help.
