HTC SENSATION XE SWAP FOR IPHONE 4/4S OR ANYTHING ELSE REASONABLE ?

I have a htc sensation xe for swap, would ideally like to swap for an iphone 4, or 4s, any memory or colour, but must be on o2, and be in good condition. The htc is in good condition, only a few months old, on o2, no scratches on the screen, comes with all original accessories and box, however : DOES NOT COME WITH DR DRE BEATS HEADPHONES, i sold these the minute i got them, the quality of them were awful, however if you are that desperate for a pair, they are about £20 on ebay. Will swap for another non iphone reasonable phone, like galaxy s2, or something similar, just make me an offer! Text on 07738832901, dont call. can send pictures if required. I WILL NOT SHIP.
