GPS Cell Phone in Soda Can Form

andyf Re:lets get to the important Slashdot question... (301 comments)

That link says "The phone itself reports GPS signal information to the cell towers which combine that with their own information." which to me means it's GPS plus triangulation. And yes, I have that phone, and mine says "GPS" on it too. But it's obviously more than just triangulation, because otherwise the phone wouldn't have to 'report' anything beyond its regular voice transmission.
