Ever since I downloaded OS 6.0 on my Blackberry Bold 9700, the device will not update my calendar information. I do the backups, and it tells me the backup is complete, but it will not transfer the data from the device to my computer. I have tried restarting my computer, removing the battery from my Blackberry, and backing hitting "backup" and also "Sync all" and it doesn't back up. Any suggestions? It worked perfectly with OS 5.0.
