RIM has pushed out an updated version of the BlackBerry Tablet OS simulator, complete with a fully embedded BlackBerry browser so that would-be PlayBook devs can test out their web-apps, Flash 10.1 and general site performance. In addition to the Adobe support, the PlayBook will also handle HTML5 Video and Audio (though the simulator doesn't have the full range of codecs that the final hardware will).
The updated BlackBerry Tablet OS simulator - along with all the relevant documentation - can be found here. It's available in versions for Windows, Mac and Linux. For more on the PlayBook itself, check out our hands-on report from back at CES 2011.
