I would guess that the GPS is an "assisted" GPS and a lot of the "smarts" is
in the cellular system (e.g. Satellite almanac, etc.). All the thing in the
phone does is start with a presupplied estimate of position and get code
phase for some subset of satellites, then do the nav calculation, most
likely with help from the cellsite.
