Federal Communications Commission and Federal Trade Commission have opened parallel inquiries into smartphone security updates. The FCC has sent letters to AT&T, Verizon, T-Mobile, Sprint, and U.S. Cellular asking for information on their processes for reviewing and releasing security updates for mobile devices. The FTC has asked for similar information from Apple, Blackberry, Google, HTC, LG, Microsoft, Motorola, and Samsung. The two agencies say they are responding to the growing amount of personal information held in smartphones and a rise in the attacks on the security of that information.”]
