I don’t know that I would call LinkedIn my favorite social network, however, it is certainly the most useful and it just got little better.  LinkedIn for BlackBerry version 1.2 has been released and it significantly improves performance as well as fixes other bugs.

We’ve just released an update focused on performance, battery life and resolving several issues our users were seeing with downloading connections. We made a number of changes to how we handle merging your address book with the BlackBerry Contacts application and other changes that should significantly reduce the battery life issues some users have reported.

You can download LinkedIn for BlackBerry 1.2 from http://m.linkedin.com/blackberry/download or pick it up on BlackBerry App World.
