I'm a registered developer, although I haven't yet paid the $99. That being said, I have no way to read the b1-b2 upgrade instructions (paid developers only). Now I fear I may not be able to upgrade and my phone may be bricked when b1 expires. Surely Apple must let people like myself know how to upgrade... I don't believe I did anything wrong. Anyone know what these secret instructions are, or when the expiration date for b1 is? I can't be the only beta tester getting caught in the middle of this. I fear my only option is to just get the update via p2p and install on a wing and a prayer.
