(I do not have a 3G account and this works.) Because of the way the cellular system works, each tower has a GPS location already calculate. The iPad then triangulates a more exact location. 

This explanation is more or less backwards of how it actually works, but I think I am going to give up attempting to explain this, or re-quoting the Apple site as I did earlier. I haven't the patience.
