So I just tried to update to 4.2 today, and iTunes sat for ages on a screen that said "verifying download with Apple" or something like that, with the iPod displaying an Apple with a progress bar that isn't filled at all... iTunes eventually timed out and said something like an unknown error has occurred, and then...that's it. If I disconnect and reconnect the iPod, Windows makes the sound that it's recognized a new USB device, but iTunes doesn't 'see' it. Is there a way to force a firmware update or something? Is sending it to Apple the only option? EDIT: I should mention the hardware buttons on the unit seem to do nothing while it's in this mode. It seems like it ought to be possible to force a firmware update or something!
