I come from a Motorola Droid X. As most know by now, it has never had an unlocked boot loader
. Unlocked boot loaders allow you to install different "kernels"
The phone was rooted
early on and thousands including me did and are still installing custom roms
on the phone.
Getting root means a developer does indeed have the ability to make many changes to the operating system. This would be called a custom rom
. A fully unlocked boot loader means a developer can completely change the kernel
. This would allow you to install a completely new OS.
The words root and rom can indeed be used in the same sentence.
I do agree 100% however that doing either can cause your warranty to be voided! Be very knowledgeable of why/what you are doing before hand
