Those AT&T customers running an Apple iPhone on iOS 6.1 or higher, will receive the update OTA. Others will have to wait until they update their software next via iTunes. Apple iPhone 4, Apple iPhone 4S and Apple iPhone 5 users are said to now be receiving the update. The program was developed by the FCC and is required by law.
AMBER alerts, which deal with missing or abducted children, come directly from law enforcement officials and can be disabled. Imminent Threat alerts, which deal with an approaching risk to personal property or life from a man-made or natural disaster, can also be turned off. When the update arrives, users will receive a short message that the carrier settings have been updated. By default, the messages will be turned on.
