The video above is with Ryan Bidan, senior product manager for the PlayBook, who gave Engadget a hands-on demo of BlackBerry Messenger on the PlayBook. It's not a native app - which means you'll need the PlayBook to be paired with a BlackBerry smartphone via BlackBerry Bridge. The BBM update for PlayBook was announced yesterday and is being pushed out to users - along with a Bridge update on the handset side. We imagine a stand alone version of BBM for PlayBook will be available in the future, but for now, this should hold off all of us BBMers out there.
