Location Assisted GPS and GLONASS Im trying to understand the iPhone 5s GPS capabilities. Especially for GPS when you are out of range from a cellular signal, T-Mobile's network sucks... So I want to know if I am SOL without a signal... From the above spec Assisted GPS works with the cellular towers? Y/N GLONASS is a Soviet --- Sorry Russian -- GPS equivalent - Suppose to be better than GPS and recently updated? If I have cellular contact this will be the assisted GPS determination of my location? Y/N GLONASS is selected if cellular is not available? Why did an american company... Sorry Irish company... pick GLONASS? In a strict definition the 5S does not use ANY american Global Positioning Satellites?
