I've downloaded and installed calendar patch successfully, now how I do get rid of the old duplicate entries. I went through Desktop Manager/Backup and Restore and cleared the calendar (which I read about in another thread) in Device Databases. This does not clear the calendar in my BB. Why? How can I clear my BB calendar then re-synch to eliminate all the duplicates?
I had this issue, and had to extract a .csv file with my entries, modify it to show no entries, then upload it back onto my BB. From then on, if I need to clear my calendar, I have been able to use the Backup/Restore part.
