Apple Iphone 4s - Black 16g ?

I have for sale my Iphone 4s Had this phone for two and a half months but going back to my blackberry.. There bit too complicated for me... Phone is on 3 network I presume they can be unlocked as I unlocked my blackberry which was on 3 network before. Phones is in as new condition just a wee scuff on top side of phone from the case I had on it. Does not affect phone at all.. Phone comes with all original box and accesories. Accessories have never been used.. If interested send me an email :)
