We've found an interesting little report of a nasty practice instituted by Motorola on it's customers of the Droid X smartphone.
According to MobileCrunch, the Droid X is locked down with an authentication chip called an eFuse.
The eFuse verifies the bootloader, which is the first process to load. It is filled with all the important stuff like the core software of the phone. If the eFuse doesn't see specific, pre-programmed code within Motorola's guidelines, it will essentially short out and the Droid X will cease to function at all.
What does this mean? No hacking. No jailbreaking, literally. It will ruin your phone.
In order to revive the the phone, one needs specialized hardware only found at Motorola. Awesome, right? Your phone is not your phone! It sort of puts a lie to the idea that the Droid platform is all about openness.
Hopefully Apple doesn't cotton to this idea, it would be hell for the jailbreaking community.
