Ok, so I synced my Google calendar with the BB. Now I have another google calendar for business. Can I sync both? I have not been able to. If not how do I change it from my personal to my business calendar?

You can sync them both, yes... but you can only choose one that will sync from the blackberry back to google.

You can find more info on Google Sync through their help page
