Is it legal: yes. Will it void your warranty if you bring it to a VZW store as-is: yes.

Its kinda like the tag on a mattress...Sure, you can rip it off, but once you do you're gonna have a hell of a time trying to return it. If you choose to do it, back up your stuff and remember to do a hard reset/return to factory spec before visiting VZW.
