Samsung Galaxy W unlocked (SWAP) ?

i have a Samsung Galaxy W and am looking to swap for other good phone preferably an iphone of some sort, but will also consider others, preferably unlocked but if not i can unlock it myself... no blackberry though sorry this phone goes for £200+ in shops so sensible offers sorry for bad webcam photos but i use my phone as a camera so have nothing else to take pics with phone is in good condition with normal wear, only a few months old but i dropped it shortly after getting it and it has a few marks on the side as well as one on top, have shown them in the pictures, apart from that phone is in perfect condition with no scratches to the screen at all phone has android, 5 MP camera (and front camera) big HD touchscreen, headphone jack, etc phone comes with charger and a black case but no box as i threw that out
