Cell triangulation is based off of signal strength and calculations based on cell tower base. It's an old, universal system that pre-dates aGPS. It is also a lot less accurate, hence the 1/3 to 1 mile variance on location assessment with "My Location". It works on Sprint just as Live Search (for non-WM devices) on Sprint uses triangulation as well.
Why it does not work on Sprint currently either has to do with Google not making it CDMA compatible or Sprint somehow not allowing it.
aGPS uses your location merely to tell the device what satellites (out of dozens, a lot are not relevant) to look at for data, reducing signal acquisition. It also can help compute the GPS data for faster location identification.
