@neuralic, one of the DingleBerry creators has just released the video demo above showing the power of the DingleBerry Jailbreak. He demos the Android Market, Android Native Email and Google Apps on his device. However, due to some limitations with the PB Android Player, he was limited to what he could install from the Android Market. Still, this is exiting to see the PlayBook becoming a customizable workhorse as we are exited to see what next the DingleBerry team brings to the PlayBook tablet. He also mentions that they are working on releasing a Jailbreak version that will be more user friendly to install for us laymen out there. We'll keep you updated as more comes in.
Have you been able to root your PlayBook and install some of these cool features?
