This hadn’t occurred to me till someone mentioned it, but you can save a hundred bucks on an iPhone by getting a “certified” refurbished unit from Apple. I’ve never bought factory-refurb’d from Apple, but I know those who have and they’ve been happy with the purchase. They currently have 4GB phones for US$399 and 8GB models for $499. So you could get an 8GB iPhone for the cost of a 4GB phone. I’m in the market for an iPhone, so this is more than just an intellectual exercise for me. I might go this route. If I do, I’ll let you know how it goes.
