An FCC mandate for a Wireless Emergency Alert system implemented on mobile devices is now being delivered to iPhones by AT&T, the country's second-largest carrier. The government-issued messages will appear in a manner similar to text messages, reports AppleInsider, but are actually delivered by a different and faster system (at no charge to the user). They will include mandatory Presidential alerts (issued by the White House), and the option to receive Imminent Threat alerts and AMBER alerts.
