Nothing, accept for the fact that if you **** it up, you will do everything in your power to get it warranty exchanged out on verizon/motorola's dime. They dont want that. In turn, they made a fail safe for them to know if you messed it up. And ALSO, they provided a fully featured phone that has everything all the other leading phones have so you may be compelled to NOT mess with it. My point is, its never going to be everything for everyone, but it will for the majority. And for the rest of you who will mess it up, you will now be penalized for doing so. I for one am glad they did this. I too modded the hell out of my droid, but because it was physically slow to register finger touches, and would lock up when multitasking like they claim it should be able to do easily. I tried 3 seperate phones to no avail, so I decided to root then overclock. It made the 3rd phone do correctly what they advertised it could do from the factory. Essentially I made it work right.
