Hey Agentfruit...joonyer here.
Spend the $30 odd bucks on Missing Sync for Blackberry.
The Missing Sync for BlackBerry - Synchronize Mac OS X and BlackBerry
Works great for just about EVERYTHING...however, I also have Curve 8310, and use the free app "pocket mac":
PocketMac - The Original Mac-to-Pocket PC Sync Solution(TM)
I have to use Pocket Mac for "sending" Applications to Blackberry.
If you for instance, download "Date reminder" for Curve to your Mac, to "get it" to the blackberry, you will use Pocketmac. Look for the .alx file and load it to the BB. It will be under "Utilities-Install software to Device". This gets any app to the BB. Missing Sync will do everything else you need!
Cheers!
