The Droid 3 is the most powerful Droid to date -- its 1Ghz dual-core OMAP processor and Android 2.3.4 make it a speedy and capable device. As with most devices, D3 owners wanted root access in order to take full advantage of all that it had to offer. That day has finally arrived, as the D3 has been rooted by developer drjbliss from the XDA forums.
The rooting process seems to be rather easy, granted you have ADB set up and know how to use it. The vulnerability was found in some proprietary Motorola code that allows specific files to be edited and manipulated into achieving root access.
