Ever since I got my blackberry I've been syncing via desktop manager with the usb cable. On occasion I would leave my home to go on appointments and forget to sync up. Then in the middle of the day where I think I have a couple hours I get a phone call "Hi, are you almost here?" I make up some BS like "Oh I though our appointment was tomorrow, but I'm free now so I can come right over. I don't have your address handy can you give it to me again.":p So I get home and sure enough Outlook reminder is popped up with their appointment!! That's happened a few times. So I've been searching for a solution to do OTA sync. I found a program called gsyncit because I was considering moving to android and wanted to make sure I could still use Outlook. Anyway purchased gsyncit installed it and set it up in outlook and synced to my new gmail account and then I downloaded google sync onto my blackberry and pointed that to the same gmail account. And bingo calander and contacts sync OTA automatically!!
