Along with an error while upgrading, that was fixed by going through the process once more, I had problems with my email. Despite backing up everything and re-entering the email account information, all I could do was receive under a generic messages icon, for about an hour. Attempts to send or forward were greeted with an error message that essentially said I had no email accounts activated. Now, other than losing about half my 3rd party apps and all archived messages, everything seems tickety. Anyone else have a similar experience?
