I just upgraded my 8330 from 4.5.0.77 to 4.5.0.89 using the Advanced Procedure here like I always have. I did this while VPN'd into the company network so it would automatically reactivate me on the BES. This seems to have worked because new emails sent to my work email address are being delivered to my device. However, now my Calendar is empty and does not seem to be syncing wirelessly. My Contacts are fine. I've rebooted and resent service books, but still no calendar entries. Ideas?
