I'm selling a black iphone 4S 16gb. It's unlocked and works perfectly on any GSM carrier. Has been tested on AT&T, T-mobile and overseas with pre-paid sims. It's in good condition with normal wear and comes with the USB cable and an Encase slider case that I'm throwing in since i won't have a use for it after the phone has been sold. https://docs.google.com/file/d/0BzmJQtBUyBsbTHpvazFnYWRkVG8
