Apple iPhone 4s 64gb black ?

Apple iPhone 4s 64gb black this phone is in very good condition. I bought it in a car boot sale, when i took it home it would not work on my sim card. I took it to a shop they told me it is locked to an American network. It would cost me to unlock the phone so i left it, the phone seems to be in perfect working order with screen protector still on the phone. sorry no accessories.
