I've had the iPhone 4 since around about release time, no contract, no ties. I will be buying the next gen iPhone regardless of the rumours/leaks etc........ Question is, am I too early in selling it, in anticipation for the new one coming out September!? I want to get the most money back for it. Bought it sim free for over £400(can't remember exactly), was nearly 2 years ago. Thanks, Stuart.
