On a side note, in the US there's no actual requirement for cell phones to have GPS. They can use triangulation off of cell towers, so long as they can get the required accuracy.
Huh. I remember hearing that a lot of phones would cut back to 2G (this was a couple of years ago) when you were calling 911 so that they didn't have to use GPS to get the required accuracy which I guess was only required at 3G or 4G connections.
