I'm not even going to bother Rooting either of my Droid 3's From VZW (I have 2 of them) until there's at least some custom ROMS and all out there for them...
Really people, what's the point in rooting your device unless you can actually make your own customized ROM/Tweak your software/Etc. ???
I'm holding off for some nice stable Custom ROMs to come out because as of right now, the Droid 3 is a Beast and Runs great with everything I throw at it with no problems at all and right now they're both just stock ROMs with a bunch of apps n stuff...
