Trailrunner7 writes "The researchers who last week said they had succeeded in jailbreaking the RIM PlayBook tablet have now posted a detailed walkthrough of how users can accomplish the same task on their own. The technique requires the use of a custom tool, but otherwise is fairly straightforward.
One of the researchers, known as Neuralic, posted the walkthrough to Pastie.org Tuesday morning. In order to begin the process, a PlayBook user need to first install the beta 2.0 version of the PlayBook software and then install the Dingelberry tool, which exploits a weakness in the PlayBook architecture which stems from the fact that the backups that the device takes aren't signed, according to a message posted to Twitter by one of the researchers, Chris Wade."
