unlocked iphone 4 32gb .

i have an unlocked iphone 4 32gb good condition,couple of light marks on screen. only fault with it is the buttons at side do not work so it is always on vibrate, they say this is a software problem affecting quite a few and it should be solved with next update. once the headphones are connected you can control volume etc does not have box only charger will not POST or accept PAYPAL
