Apple Iphone 3gs 16gb - O2 ?

I am selling an Iphone 3gs 16gb, it is locked to O2. It is in good condition, the screen is in very good condition, with only a few minor marks. The back is also good, with a small crack at the bottom, which is purely cosmetic. It is all working fully, all the buttons are functioning perfectly. Can deliver in area if needed. 120 ONO - Call or text anytime.
