Apple iPhones and 3G iPads are secretly recording and storing details of all their owners' movements, and the location data is kept in a hidden, unencrypted file according to security experts, BBC reports. With the right software, it can be used to map exactly where a person has been.

Apple has yet to comment on the revelation, but there is no suggestion that it has been uploading or using the information.

The findings will come as a surprise to most iPhone users, as their devices do not give any visual indication that such data are being recorded. (点击BBC网站查看原文)
