Endoflow2010 writes: The developers of the hoped for Dingleberry 4.0 application that was allegedly going to provide root for the BlackBerry Playbook OS 22.214.171.124.7971 have canceled their project. One of the Dingleberry developers Xsacha says. "The funny part is it is still possible to root 7971, just not in any way viable for release." Yet hacker Chris Wade says, "I haven't given up on dingleberry (xsasha posted something but he doesn't speak for me) I just haven't had time to do any work on it lately." While some may have given up on the project the developers did give others hope for the future. They have released the source code for Dingleberry 3.3.3.
