Apple IPhone 3gs - on orange +

Apple iphone 3gs 8gb locked to orange, bought this phone from a seller on here on the understanding it was unlocked, the seller lied and never had it unlocked so selling at the same price to recoup my money. Screen is excellent condition no scratches, the back of the phone has light marks. Have replaced the sim tray too as that was damaged when I purchased it from here. comes in original box with charger, headphones and usb cable, orange sim card included. Also screen protector and a black gel case. I will not swap for anything so please do not ask, if you have any questions please email me.
