I downloaded and installed this last night. Haven't had a lot of time since to really test it out but it's running very well so far. The addition of the wifi hotspot and battery save mode are nice features. Wifi hotspot worked great when I connected my laptop to demo it.

To install this OS update; download the appropriate software for your device from the link above and install it on your computer once it's finished downloading. When the install is finished make sure the DM is closed and go to..
C: -> Program Files -> Common files -> Research in Motion -> App loader.
Once in the app loader folder DELETE the vendor.xml file. Connect your blackberry and open the Loader program. The rest pretty much explains itself.
