Great news, BlackBerry PlayBook users – the Dingleberry root has been updated to version 3.0 which introduces some new enhancements. Users can now downgrade the tablet to an earlier version of the operating system (to get rid of the latest update from RIM), and there also is the ability to unblock Hulu as well. So if these features are something you must have on your BlackBerry PlayBook in addition to Android Market access etc, head over to the Dingleberry website to download it – as usual, be sure to backup your device in case anything goes wrong, and let us know how it goes for you.
