I'm looking to sell my iPhone 3G in hopes of a new iPhone, but I'm not really excited at all about what the rumours say it'll have. On the iPhone 3G, the big selling point was 3G and a built in GPS. For the new iPhone, the only major difference will be a new/beter camera. Is that really worth justifying a new iPhone? I am hoping for a significant new feature like video calling, but according to the rumours, it's not happening.
