I purchased this iPhone 4 Black 16GB SIM-free from Apple.com/uk in August. I received it in September and have been using it for a month and a half.
The unit is in flawless condition. No noticeable wear on the phone because I always used the Apple OEM bumper.
The box and all it's original contents are included in addition to the Apple OEM bumper.
Either direct pick-up cash in Bedford or I can ship next day for 7 pounds anywhere in the UK once you pay invoice to your paypal account.
