The good news: BlackBerry Desktop Manager 1.0.3 has been released.

The application, a 31.6 megabyte download, allows Mac users to sync data from Mac applications like iCal, Address Book, Microsoft Entourage and others, as well as add and remove applications, schedule automatic backups, encrypt backup files and install software updates for their BlackBerry smartphones.

The downside: Because Research In Motion is apparently run by staggering idiots who think the cast of “Jersey Shore” qualify for Mensa status and unicorns are real, absolutely no version changes have been logged or mentioned.

None.

So, if you’ve installed the new version and noticed any changes (for better or for worse), we’d love to know.

Especially since the developers of this long-awaited software package seem reluctant to tell you what they are.

BlackBerry Desktop Manager 1.0.3 is available for free and requires Mac OS X 10.5 or later to install and run.
