Combination of device/software that will let me access/sync multiple calendars?

[dmorrocco]

From a relative bb novice...

I was wondering if there was any combination of device or software (or upcoming device/software) that would let me keep synced two separate calendars on a blackberry?

I have two separate accounts at work (using BES and Outlook) and would like to be able to access the calendar for each on a blackberry of some kind, preferably in a fashion that would sync over-the-air.

Apologies if this specific question has been covered recently - but I was hoping perhaps with the new version of the OS on the way help would be forthcoming...

Thanks in advance for any advice.
