Verizon GPS question....

Ok I am a Sprint customer and so I cannot varify this so I am asking you guys.
I want to make sure that verizon users can get GPS working on my ROMS. So here is my question.

In theory if one would flash the new Verizon Stock ROM that unlocks GPS and let it customize and then flash a custom rom would GPS still work?

If not, then all they would need to do is install and run the PPST to unlock and provision the radio, correct?

Thanks for your help
