hi guys, i would like to buy a couple of i phone 4s to sell on eBay. I recently had a contract with ATT but it just ended a few months ago. What would I need to do to pick buy a couple of these iphones to sell on eBay? Once, I had a 2 year contract with them and have the iphone 4. can i buy more iphone 4s since now I got a contract? if the phone is already activated and it has service on it under my name, how can i get rid of that? so i can sell on eBay? answers appreciated.
