All of Motorola's recent devices (save for the XOOM) have featured bootloaders that are locked down like Fort Knox, and despite publicly stating that they would be reversing that policy, the company has yet to take any action. Although they stated they wouldn't begin making bootloaders unlockable until late 2011, many people held out hope for the newly-released Droid 3. An apparently lost hope, unfortunately, as a Motorola Support forum admin has confirmed that the hot new Droid is as locked as its brethren.
Motorola painted a big bull's eye on itself when it started locking bootloaders, and now the company is certainly taking its time remedying the situation. Hopefully they get to it sooner rather than later - and in the meantime, hopefully the hacking community can work something up.
