I have a calendar program that I would like to sync with the BlackBerry, and I don't want to go through Outlook or any other calendar, I want to sync directly with the built-in BlackBerry calendar. I'm pretty sure Google Calendar does this by using the PIM API.

Has anyone else done this? It looks like Google probably relies on event notifications for detecting changes to sync from the BlackBerry, I wonder why they wouldn't have used the modification time of each record to look for changes? Maybe too slow to loop through all events on the BlackBerry and check this field every minute or so (every sync). I've read that event notifications don't always fire the way you would hope, so trying to synchronize based on that could leave you out of sync.

Anyone have any words of advise on this topic?
