i have no idea what happened, but after unplugging from my pc to add a few mp3, the market won't open, it says "You must add an account to the device to continue." and when I click yes, it disappears. G-Mail doesn't even open. I synced it this morning, but nothing. the apps themself are still there, but I can access them. Actually, I think it's google apps in general, I tried opening "G-Talk" (not even sure what that is) and it does the same thing. Also, youtube app is gone. it's in my settings -> manage applications folder, but not in the app drawer. please help, and please don't tell me i have to reboot or something.
