Apple iPhone 3gs 16gb White in Tonbridge, Kent for sale

Here for sale I have an iPhone 3gs 16gb in white. I think it is locked to o2 but will also work on tesco and giffgaff if this is the case. the phone has a few scratches on the back and a small crack on the rear casing but is minute, was purchased second hand but i have always had it in a case so haven't taken any notice of the scratches anyway. Selling as i have now upgraded to the 4s so is just sitting in the drawer taking up space. Ths has been a brilliant phone but still believe it as a lot of use left in it. The battery life is decreasing slightly so may need a new battery at some point, but these can be purchased for around five pounds. The phone will come boxed with headphones, sim opening tool and genuine apple usb lead. any questions please ask.
