I have a droid x that is in prime condition, and a droid x2 that is well used but works well, what I have in mind is to take the motherboard out of the x2 and put into the x to have a prime case and the faster processor, I also thought of just changing the cases, but that seems to be a lot of work, then just changing the motherboard. the isn is the only thing thats worries me. but in effect it should just follow the motherboard.
