I'm almost 100% sure I want to get the new iPhone when it comes out next week, and in order to do so I would like to be able to get some cash from selling my current iPhone. Since there are still so many details up in the air, I kind of want to wait until after Steve Jobs' keynote on Monday until I even list my iPhone on EBay. Do you think I would be able to get more money for it now, since people don't really know what Jobs is going to announce?
