In May 2012 several U.S. carriers started rolling out a nationwide wireless emergency alerts (WEA) system for wireless subscribers. The free service is intended to share information about natural disasters and other location-centric news, like AMBER alerts.
Over the weekend AT&T announced that it is bringing WEA to its iPhone 5 and iPhone 4S owners across the country. The service will be enabled via a carrier firmware update that has started rolling out to subscribers on iOS 6.1 and higher.
