HTC One S - Brand new in box (orange) ?

Hi, I am selling a brand new HTC One S - Black on Orange Network which I got from a recent upgrade which I do not require. The phone is sealed and unopened and looking for a new owner. Ideally, I would want to sell it for £350 but open to negotiation - I will leave ad open and go with the highest price Please contact me if you are a genuine buyer. I would require cash only - on a face to face sale. 07527875352
