I'm selling my original 4 GB iPhone as-is on the forums here, but if no one grabs it, I'll put it up on eBay where the world turns bizarro. So how do i take advantage of that? What software version should I have on the iPhone? Should I jailbreak it and unlock it? What should I do with the SIM? (I plan to start a whole new account with the iPhone 3G S, so I am not planning to transfer my SIM). Any other tips? What should I use to accomplish the stuff above?
