Get Real GPS not WiFi GPS

There's a thorough guide on how to write a plugin to obtain data from the GPS sensor on Android here: http://www.mat-d.com/site/unity-gps-plugin-development-tutorial-building-a-android-plugin-for-unity-with-eclipse-and-ant/

It might me late for an answer but just in case somebody else might look for something like this in the future I would like to add that Input.location.lastdata actually uses the GPS function on android and gives pretty accurate results as well (for the latitude and longtitude at least).

I am using the code that the documendation has with the Input.location to retrieve the information without having wifi or 3g enabled on my phone.
