Apple iPhone 4S White 16GB ?

Mint condition, Locked to 3 atm but can be unlcoked to any network at an additional cost of £15. Only thing is has a very minor chip to the top left of the phone, if this is a problem I can have it replaced with a new one from the Apple store. Screen is spotless, has had screen protector on since opened box about 2 months ago. Comes boxed with all your accessories. Open to sensible offers, give me a buzz/text - 07837903914
