There are ways to find a cell phone within a city without GPS. When a cell phone is within range of a number of different cell cites, the signal strength is compared among the sites. Using this, it is possible to triangulate on the position of the cell phone and to locate it within a couple of hundred feet. Sometimes even closer. I forget the actual specification required by the government, but it's fairly close. Much closer than most people think.
GPS just makes it easier. Technology can be amazing.
