Android developer c21johnson has worked up a custom ROM for the Motorola Droid X2. Minimal X, currently in a beta-release stage, is the first available custom ROM for the X2, which still has a locked bootloader. Goes to show that keeping phones locked down won't stop dedicated people from hacking at them, and it a huge waste of resources, and I'll stop there before I go off on a whole 'nother tangent.
The ROM itself has been cleared of any useless bloat, and the system and framework have been edited. As the developer mentions, this makes a great base for some more exotic work to be cooked from, and we expect to see it soon. Of course you'll have to have root, and ignore the drama and use the bootstrap utility that is floating around out there to install. Looks like the X2 is following in its older brother's footsteps and has turned out to be a capable, and hackable, piece of gear. Congrats c21johnson.
