Is there a way to find out if iPhone received CLLocation from A-GPS, cell signal strength or Wi-Fi?

Question

Am I trying to find a property that indicates how the iPhone physically gets CLLocation?

As far as I know, iPhone gets CLLocationthrough:

1) GPS 2) Cell tower triangulation 3) Wifi ID and signal strength

Can I programmatically reference something in public libraries to get this?

If there is no way to identify it programmatically in public libraries, is there a way to "circumvent" the same information?
