Iphone 4 16gb Used but superb condition. ?

For Sale is my beloved iphone 4 16gb in Black for sale due to an upgrade. I have really looked after this phone, its in excellent condition with only a faint scratch on the back and since that scratch occured It has had a case on it ever since and its never been dropped. Comes complete with the usual charger and a pair of headphones and sim opening tool and if I can find the box you can have that too. Please feel free to ask any questions...
