Iphone 4 on orange for sale, boxed with charger -

I have for sale an iphone 4 locked to Orange. Everything works as it should but there is a small crack on the back glass housing (replacement part is under 5 on ebay) Comes boxed with charger. A couple of minor scratches on the back but the screen is in great condition as id the silver bezel. Will accept trades but wont take less than 250 cash.
