Can I Change My iPhone To A New iPhone?

I Currently Have An 2 Year Contract And Not Eligible For An Upgrabe Until 2015, But I Want A New Phone. So Can I Buy An iPhone At Apple And Connect It Through AT&T Or Do I Have To Buy The Phone At AT&T?

You can buy an unlocked phone for $649, $749, or $849 (depending on the storage) at the Apple website and activate it. You would still be on contract though.

Your best bet is to go through eBay; and sell your old iPhone in good condition. Wait 2 weeks from now when you see a price drop on the iPhone 5, go on ebay and buy one from someone trying to sell theirs for the 5s, then sell your 4 for about 150, and pay around 400± for a new 5. Then your paying 250 instead of 500

You can buy a full retail phone through AT&T and they will just hook it up to your existing plan. Either way your going to pay 600+ ( not sure price for new iphones) So make it easy on yourself if you really want it by, buying the new phone and getting it set up and then turning around and selling old phone.
