Ok, initial report.

Just upgraded, and have the following issues:
Text size in places immediately went very, very small. E.g. conversations summary, status menu, etc

To fix this, I rebooted. I noticed lots of stock nokia stuff reappearred, like the ovi bar and default widgets. When it restarted, I got the nokia sms thing. All my widgets are missing, and when I add them, nothign happens.

The desktop also keeps restarting every few seconds.

I'm also getting a load of internal errors in calendar et al.

...contacts just sits there spinning too - no contacts
