Thanks very much for your reply.
I should have clarified:
Fortunately, my BB device (8700c) is sync'ing fine and dandy (both Calendar and Email) with my Exchange (via BES).
I'm just confused about what I read on Blackberry's comparison chart.
I just want to know what it really means if a device has the "Wireless Calendar" feature (if it means anything at all).
Also, I want to know if other devices, like 8820, 8320, Bold, etc. will calendar-sync with Exchange via BES.
I almost feel stupid asking this, because wouldn't it be insane if they didn't?
