iPhone 4s 16gb Black ?

Hi I am selling this iPhone 4s, it comes with 16gb of storage, is black in colour, has original unused headphones, charging cable, wall charger and warranty until November. I am selling this because it is wasted on me, I have another phone which I much prefer for typing and texting, the iPhone is pretty much used occasionally for facebook. Because of this is has been almost unused since I bought it and in near pristine condition. It is locked to O2 but you can pay them 15 pounds to unlock it or do it manually if you know how. Thanks any questions feel free to ask. Collection only
