Version 2.0 was on the phone, but I noticed some things that don't work. Mail.app crashes immediately on load and returns you to the home screen. I have tried multiple restores of the firmware, but the results are always the same. Mail just doesn't work now.
Logan suggested I delete the mail account and recreate it. Sounded like a good idea. I go to the settings screen and choose Delete Account and it doesn't do anything. Account is still there.
On the phone side of the phone, voicemail no longer works. I guess people can leave messages, but I can't access the voicemail. Half the time when I try to access voicemail, the phone app crashes.
All in all, not that impressed with version 2.0. I have spent some time today trying to downgrade, but that's against Apple religion, so I guess I'm stuck with 2.0 until they release another update.
I have set up an appointment at the Apple Store in Kahala tomorrow to see if they can fix it (if they could just downgrade to 1.1.4, I'd be happy with that).
