RIM keeps on rolling with Desktop Manager for Mac. They have just opened up a new program in the BlackBerry Beta Zone for Desktop Manager for Mac v2.0. From what I can tell it seems like this program is limited to North America only but let us know if you manage to get into it from other continents.
Just head on over to www.blackberry.com/beta and login/register to join the program. Let us know if you run into any issues!
