A Patent filed by the American based Apple technologies firm, has some worried. It allows authorities, businesses, networks, and others in positions of power to shut down your phone's ability to communicate, or disable its ability to take pictures etcetera based on your GPS location, or the nearest base tower.
Apple explicitly mentions the use of this by a government to insure a blackout as one intended use. Other uses include preventing copyright infringement in theatres, and protecting sensitive business and classified information.
Mobile phones have played a vital role in preventing police and security forces committing abuses.
Apple Inc. (Cupertino, CA) now holds the patent, filed in June 26, 2008, granted: August 28, 2012.
