I have an IPhone 3G (16GB)that was manufactured with the wrong back put on it. The phone is a 16GB with an 8GB back and labeling put on it. In the settings it shows it is 16GB all numbers have been verified by my local Apple Store and the were amazed. I wanted to exchange the phone and the Apple rep suggested it might be worth my while to keep it since Apple rarely makes this type of error in production. Any suggestions where to start?
