BlackBerry has updated BlackBerry Link, this includes both versions for Windows and Mac. Windows is at v184.108.40.206, Mac at v220.127.116.11. The update is nothing big, just bug fixes. Still important though, since bugs can be a problem.
RIM recently released OS 18.104.22.1688 for the BlackBerry PlayBook. There were quite a few improvements that came with this update but there were also some problems that have reared their ugly head as well.
