iPhone 4 Black 16gb For Sale ?

I am selling my back 16gb iPhone 4, simply because I now have a white one. A few minor marks round the edge and minor scratches on the screen. Works perfectly, no faults with the handset. Phone is on O2 but was purchased from Apple so believe it will work on other service providers. Comes in box with charger Looking for 240 ono Call 07708743518
