The big news this week from the world of Apple was the discovery that iPhones have been tracking users' locations as they go about their daily lives. Apparently, whenever you use Google Maps, or take a picture, or do anything that consults the GPS, your location and a time stamp are recorded in a log file on your iPhone. Apple is not using this information for anything, but it's not surprising many people find this particular previously unknown feature pretty unsettling.
