I have a used 16GB Apple iPhone 4 that is factory unlocked and on iOS 6.0. The phone has been restored to factory settings and can be used with any carrier that uses a SIM card. It was originally on AT&T. It has a small chip that is unnoticeable with the case on and a few scratches from regular use on the front. The back plate is brand new so camera is really clear. Looking for $180. Comes with USB sync cable and case but no charging block, box or earbuds.
