Can anyone shed some light on the differences between Goggle Location Services, Standalone Location Services and Verizon Location Services, all located under the Location and Security Settings. Do I need all of them checked? I have a Nav system in my car, Wireless at my home and I do like to Check In at locations through FB. So, I am completely lost on which one of these I need to use. Also, I live in ATL, GA so converage is 4G.
