iPhone 4 (network problem) .

here i have a light blue iPhone 4 for sale, the screen and back are in mint condition as i recently removed the stickers and both the screen and back are in immaculate condition with no scratches what so ever. The phone comes with the box and its original charger, the only problem with the phone is the signal, the phone could either be on orange or tmobile i am not too sure, open to offers or decent swaps, just let me know what you have.
