So what about all of the 3G phones that are "being seeded to reviewers" and have already been shipped to stores? What build of OS 2.0 are they running if the OS is still in development, with the GM build declared tomorrow?
They'll be running the last beta. When the phone is first plugged into itunes it'll probably pop up 'your phone needs an update for the latest cool features' or something like that, and update to 2.0 release automatically.
