The BlackBerry PlayBook has just become the first rooted BlackBerry device, and developers xpvqus, neuralic, and cmwdotme are preparing to release their rooting tool, dubbed DingleBerry. Neuralic can be seen below demonstrating control over the backlight and other system features, and has shown the device running Hulu in another video.

The video shows the PlayBook running BlackBerry Tablet OS 1.0.8, but neuralic claims the root also works on the 2.0 beta, and that rooting the beta allows access to the Android Market. Rooting persists after the device is rebooted. Besides giving users access to new features, this could mark the first step towards getting the PlayBook to run a custom OS, making the PlayBook more attractive to people who agreed with our assessment of the current software.
