Apple Iphone 4 Black 32gb unlocked
Excellent condition with no visible marks or scratches. This is the 32Gb model and is jailbroken which means you can download games and apps for free. The phone has tomtom sat nav installed and comes boxed with a charger, free screen protector, and aluminium case. No timewasters please.
