The DingleBerry tool for the BlackBerry PlayBook opens up all kinds of new possibilities for hardcore users everywhere. While there isn't too much you can do just yet, many PlayBook owners have had plenty of sleepless nights pushing the tablet to its limits and finding new things to do. One of which comes from eltecnoblog and shows off a rooted PlayBook with a USB support (much like what was shown off by the guys at TAT). As seen in the video above, the PlayBook is able to read a USB flash drive and play movies from it thanks to some hard work and a bit of hardware. It's definitely a great start and a good sign of what can be done on a rooted PlayBook. Check out the full video above, then drop a comment with your thoughts!
