I think I discovered something alarming. In iOS 5 there was a location setting called "Traffic". Most people left this on assuming without it they received no traffic in maps. The actual toggle controlled the crowd sourcing feature of traffic. Your phone transmits your location and speed to apple to improve traffic. They did this in iOS 5, I suspect, to build critical mass of data before releasing iOS 6. So, in iOS 5 I turned this off and saw nice battery improvement. When I upgraded to iOS 6, I opened the new maps and clicked traffic only to get an error that Traffic was disabled and to go to settings. I go to settings and BOOM, the traffic toggle is gone. apple has removed it! My toggled OFF must still be in the plist file. Resetting all settings fixed the traffic issue What does this mean? It means you now have NO CHOICE in reporting traffic data to Apple. Not only is this a privacy concern, but it chews on battery. Is this even legal to prevent us from turning this off?
