iPhone 4 16GB for sale - Excellent conditionBoxed ?

iPhone 4 16GB - Black version - for sale (not the 4S version). The phone is in excellent condition and is boxed. The screen has always had a screen protector on it. I have taken the screen protector off to show anyone its condition but have a spare screen protector included so that you can attach a new screen protector. Chassis, back and body is in excellent condition. Again, always had a silicone protector cover on it. This is included. Phone is currently on 02 but I believe it should be unlocked to all networks.
