Apple iPhone 3G - 8GB - Black locked to o2 ?

used condition iPhone 3G , phone comes only with charger and usb cable Lots of light scratches to the front. Back has totally lost its shine but has no cracks. Phone is in full working order. The screen seems to have a few spots that are brighter. Only really visible when on light back grounds. Apart from that its a great work phone. And with a case would look great. really bargain i phone 3g full working 70
