You don't need data connection to get the GPS to work on Sprint or Verizon. You technically don't even need a connection to the cell tower from what I hear, it'll just take a really long time to lock. You can probably lock internet from the carriers end, or you can also disable data connection on your phone as well. As long as you use GPS software that relies on its own maps like TomTom or Garmin, GPS should work fine.

I can't vouch for the Fuze, but I'd imagine the GPS on the Fuze wouldn't be locked down either.
