Just a couple hours ago RIM started pushing out BlackBerry Bridge v2.0.25 to BlackBerry users. In the new Bridge update includes Remote Control. Remote Control lets you the user use your BlackBerry smartphone as a remote for your PlayBook.
I am still running PlayBook Beta OS 18.104.22.16849 so I thought I would give it a try and low and behold it worked! So if you are running the beta OS on your PlayBook give it a try and let us know in the comments how it works out for you!
