This is not about the carriers locking out GPS. What this process fixes is the lack of correct information put into the GPS settings in the system. To speed up the process of GPS lock, the system looks to a server to read cell tower triangulation. This "assist" helps pinpoint your location and reduces the time that it takes for satellite communication with your GPS chip.

I can't speak for other carriers, but on my US Cellular 8330m (the new, longer MEID HEX ESN), the server was set to 0.0.0.0, or in other words, null.

This process works, and it works well!
