But we do have those GPS location phones here @ Verizon humm no comment!
When you have GPS in a phone, though, it's usually not standalone GPS, it's assisted GPS (A-GPS). A-GPS does use the satellites, but it gets help from the network and the towers to work much faster, more accurately, and indoors.
First, the network knows what towers the phone is near, so it knows the general area the phone is in. The "location server" on the network uses that info to tell the phone which GPS satellites to listen for, skipping the time-consuming "searching" step.
Then the phone takes raw readings from the satellites. Turning that data into an accurate location requires additional info...

This is the first i have ever heard that the phone would receive any direct reading from the satellites however... I'm not sure how the phone is capable of this as it does not operate in the same frequency band as the GPS signals from the satellite. A cell phone operating in 800, 850, 1850 or 1900 mhz while the GPS signal is sent out at 1575 or 1227 mhz.
How does this work?
Here is anyone else is curious:
