iPhone 4s Working 16gb White +

Hello, selling my iPhone 4s as i have two of them. it has light scratches on the screen like any used phone would but there only visible under certain light and do not effect viewing of the screen at all. there is only a few light scratches on the back, there not even visible, hat do look really closely under a bright light to just make them slightly visible. i think its unlocked but im not 100% sure though, if its not they its on 02 as thats what sim i have in it now but i do think its unlocked its 16gb white and comes with everything when bought new. there is no proof of purchase as i bought it from my mother when she upgraded and did not want the phone, i asked her about the forms that came with it and she does not know about them lol. it needs picking up from my house, i live in leeds 9 so keep that in mind if you decide to buy, i will post out if payment is made over paypal with £10 added for insured delivery but only to the uk. i can not deliver as i dont drive. ask any questions !
