UNLOCKED iPhone 4 v5 16GB 3 WEEKS OLD ?

Basically brand new, only 3 weeks old. I have just accepted a new job and one of the perks will be an iphone 4 contract paid for, so i dont need this one. More or less pristine condition, as Ive had a protective cover over the screen since I bought it. I still have the box and all the origional accessories, however my friends dog ate the headphones. But they cost £8.99 in Argos.
