Research In Motion has been working on a way to stop people from installing Beta or Hybrid operating systems since the early previews of Mac Desktop Manager, but no one knew just what RIM was planning.

Well someone has figured a way round it and we have a video of installing BlackBerry Hybrid or Beta OS with Mac Desktop Manager courtesy of the guys over at Crackberry which can be viewed below.

The video lasts six minutes and is a walkthrough of just how the process is accomplished, and if you attempt this please remember to use caution and always back up all your data.
