Privacy-conscious iPhone and iPad users beware: Big Brother is watching. The Los Angeles Times reports that Apple’s mobile devices are secretly keeping track of where users have been by logging and storing a detailed record of their geographic location in a hidden system file. According to the two security researchers who discovered the file, the data are easily accessible and can be used to build an incredibly precise portrait of a user’s movements over time, stretching back months and even years. They’ve even made an application that does just that (Mac users only). –YL
