A synchronizing calendar on Outlook Client and Blackberry.
I progressed though the help desks from Verizon Wireless tier 1 to Verizon Wireless tier 2 to Blackberry tier 1 all the way to Blackberry tier 2! W00t! 65 minutes of phone time later I have everything back but a couple events entered on the device calendar in the last few days which I will manually reconstruct.
Apparently, there have been issues across carriers with the OS 4.5 upgrade in that it can destroy the calendar database on the device so that Device Manager doesn't recognize the data and skips calendar synchronization entirely.
Time to go to bed.
