Im selling my 18 month old Iphone 3gs in excellent condition and fully working order, it is the 16gb black version and i believe it is locked to o2 as this was my network. On the back of the case there is a small crack which hopefully you can see in the picture which runs down from the X looking symbol, this has been on my phone for about 6 months and didnt affect it. Included is the original box, wall charger and usb cable. Im located in Borough next to London bridge...Only buyers from london as i wont be posting the phone.£140
