iPhone tracks users' movements. Apple iPhones and 3G iPads are secretly recording and storing details of all their owners' movements, researchers claim. Location data is kept in a hidden, unencrypted file according to security experts Alasdair Allan and Pete Warden. With the right software, it can be used to map exactly where a person has been. Apple has yet to comment on the revelation, however there is no suggestion that it has been uploading or using the information. http://www.bbc.co.uk/news/technology-13145562
