It is locked to o2 and hasnt been tampered with in anyway unlike a lot of these iphones for sale. It has been upgraded to the latest iphone 5 software. If you want it unlocked, loads of places do it for about 10.It is in great condition, the back is spotless, and the front is great. There is a TINY crack/scratch on the edge of the front screen, but barely noticeable. Apart from that, the phone is great.
