White iphone 4s 3weeks old ?

Hi im selling my white iphone 4s 16g, ive had the phone for 3weeks and am selling due to wanting the new upgrade that is due out in september. The phone is in brand new condition i have left the stickers on the front and back so that the screen has no smudge marks. I will accept offers for this phone, its a 500 phone and seeing as ive had it for 3weeks and have the box, charger and headfones im not selling it for a stupid price. I live in cardiff and can meet to give phone. Any questions please reply to this add and ii will get back to you asap. Contact number - 07854 571 327
