If you are using Desktop Manager on your Mac and plan on picking up one of the latest BlackBerry 7 devices you will need this upgrade. Todd let me know that this update adds support for the BlackBerry Curve 9380, BlackBerry Bold 9790, and Porsche Design P’9981. Not much else in there according to the release notes but falls in line with the recent update to the PC software.
