I want to sell my current iPhone to fund my purchase of the iPhone 2.0 next week (like most of us). I'll take out my SIM card, and I'll probably jailbreak and unlock it (simply because people on EBay tend to pay more for that, even though its such a simple process). I'll also delete everything on it, favorites, songs, contacts etc. Anything else you guys can think of that I should do before I sell it? Also, I'm trying to do this quickly, since who knows for how cheap you'll be able to get an iPhone 2.0 on Monday, so hopefully I'll get my EBay ad up by tonight.
