iPhone 4 - 8GB - Top condition - Unlocked - Black - Swap ideally. !

I would like to swap this for a HTC One X or a Samsung galaxy Note. The iPhone is black, 8GB, unlocked to any network. Include a spare screen protector, the hard aluminium case, comes all boxed with original accessories. (case pictured) It is a full network unlock done by the 3Network over the phone, and it cost me money to do it. I have installed Siri on the phone... just like on the iphone 4s. I can leave this on if you wish, but I can also take it off, its your preference. I would only accept cash if it was enough for me to go and buy a Samsung galaxy Note.
