BlackBerry has updated BlackBerry Link, this includes both versions for Windows and Mac. Windows is at v188.8.131.52, Mac at v184.108.40.206. The update is nothing big, just bug fixes. Still important though, since bugs can be a problem.
RIM recently released OS 220.127.116.118 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.
