Update: Apple provided the following comment to AllThingsD on the approval:
Following reports earlier this month that the Defense Department was in the process of approving iOS 6 for nonclassified communications and widespread use by government agencies, Bloomberg reports today that Apple has officially been granted approval for use on U.S. military networks.
The Pentagon already approved Samsung devices powered by the company’s Knox security software and BB10 ahead of today’s approval of iOS 6.
In February the US Defense Department confirmed plans to open its networks to 100,000 new devices from Apple and Google by February of next year. At that time the Pentagon said its networks had about 470,000 BlackBerrys, 41,000 Apple products, and 8,700 Android devices.
A number of U.S. agencies switched from BlackBerry to iPhones over the last year, while earlier reports indicate Samsung is attempting to attract more government and corporate customers with a new team of security experts and former RIM employees as well as a water and dust proof variant of its flagship S4 dubbed the Galaxy S4 Active. Today’s security approval will increase the number of agencies allowed to deploy iPhone and iPads on government networks for nonclassified communications.
