I have a 64gb unlocked iphone 4s in fantastic condition(It's been in a Speck case since purchase) without any scratches or dents. With the rumoured imminent arrival of the next iPhone, I'm quite tempted to sell my phone as I harbour hope that Apple release a 128gb iphone 5 version. Anyway how much am I likely to get if I sell in on a site like craiglist. I live in the UK by the way. --- What are the chances of Apple releasing a 128gb version of the next iPhone, as that's the only enticing feature for me. I don't care about gorilla glass, LTE and all that mumbo jumbo.
