have bold 9000. getting "synch error" message asking me to delete a particular event in my calendar before I can synch...but I don't have that date on either my device or computer. any thoughts on adddressing this? thanks.

Pull the battery and reload the Blackberry. It may clear out and corrupted data in memory.

thanks for the suggestion. tried it a couple times. still get same message. BTW, i mistakenly said it was a 9000. it's actually a 9700. any other thoughts? thanks again.

Make sure you check to see if you might have more than one calendar in the BB.
