Sitting on an iP5 that I preordered from Apple UK on day of release last year. Black/slate, 32GB. Almost perfect condition. Should I upgrade or not!? Didn't really think I'd want to, (still not sure, haha). But what's got me thinking is the residual value of my iPhone 5......the longer I wait, the less it'll be worth. Granted, I probably should have thought about this earlier and sold on before annnounment like I did last year with my iPhone 4. £300+ value for my iPhone 5...... Thoughts anyone?? Stuart.
