How does google map work on a non gps phone ?

How does google map show almost accurately your location and position even if you do not have a gps enabled phone ?

Well, Google uses nearby Mobile Phone Towers to pinpoint your location - But guess what the results won't be accurate for the end users. But is innovative idea from the Google guys, for those with Non-GPS Mobiles

The phone communicates to cell towers, if it can find 3 towers in range it can tell the distance from each tower and if it knows the location of each tower, the phone can "figure out" where it is. It triangulates its position based on the strength of the cell tower signals.

This method is not that accurate, but it can determine the location within 100m
