I currently have a phone from Att that I use but have been wanting to buy an Iphone before my contract is up. I plan on getting one off these forums hopefully... My question is, how will I set it up? I've heard conflicting reports on this. So like I said, I have a Samsung eternity phone that I use with ATT. I'd be buying a used Iphone. How do I get it setup correctly for use with ATT? Not sure what other info is needed, but please ask if you need something. I'm really puzzled as to how this is going to work. Thanks a lot.
