iPhone ain't even an iPod without service

It's unclear what technical limitation prevents Apple from allowing the iPhone to function as an iPod without an active AT&T service plan tied to it, because we really (really) want to believe the companies wouldn't arbitrarily disable a feature to keep the cash flow rolling in.

An anonymous tipster is reporting that the iPhone may only need to be activated once for the iPod (and other features) to work; continuous service isn't necessary after that -- unless you want to use it as a phone and data device, of course.
