^Yeah, first you should reset your phone (home+power until it goes off, then turn it back on).

Also, uninstall and reinstall your apps that are giving you problems. This should fix your issues. Remember to turn your phone on and off after installing new apps to keep this from occurring.

If when you went from 2.1 to 2.2 and used the "urgade" button... or after a restore you did it from back-up instead of from new... these can cause crashing issues!

The same thing happened to me today with facebook AFTER I did a reset for another reason. The phone was geting a bit laggy since the most recent Mobile Substrate and SBSettings upgrades. Fifured a reset would help as it was a while since i had sone that. The reset helped that but then I could not logon to facebook.

I uninstalled Facebook and reinstalled and it works fine now.
