Frank McPherson explained how to turn off both of Android’s location services (GPS and cell tower/WiFi) last week.
Apple’s iOS devices (iPhone, iPod touch, iPad) have a simple single toggle to turn off location services. This procedure has become a topic of interest recently after it was discovered that Apple is storing location history in a file on the iPhone.
There’s one little wrinkle to this process for the iPhone according to the Wall Street Journal (WSJ), however.
The location history information stored by Apple on every iPhone gets its data from cell towers and WiFi access points. Turning off Location Services on the iPhone stops, for example, storing location information in digital photographs. It also prevents the iPhone user from accessing maps and other location based service. However, the WSJ and an independent security researcher found that Apple’s file continues to collect and store location data even with Location Services set to off.
