Also, if you synch with Outlook, none of those events will synch with Google Calendar either. You have to choose to synch with Google only, or Outlook only. You can't do both with the BB.
If you have Outlook 2003 or above on your PC, you can install Google Calendar synch on the PC and do a roundabout update that wary. PC->Google->BB->Google->PC. Just don't synch the BB to PC.
