Apple iPhnoe 4 black 16GB Unlocked ?

Hi I have for sale my iPhone 4 in black, the 16gb version its fully working as i use it now but the front and back is cracked and i cant be bothered repairing it. apart from that the phone is in full working order and factory unlocked and comes with original charger and box with manuals and the sim eject tool 200 no offers as i said this phone is in use now so i will have to buy a new one when sold
