Our armed forces began embracing Android and iOS some time ago, and now it appears that the US Department of Defense is finally jumping on the bandwagon, too. The Wall Street Journal reports that the DoD will be announcing security approvals for Samsung Galaxy handsets, iPhones and iPads in the next couple weeks -- allowing them to join BlackBerry in the government's secure smartphone stable. Apparently, Samsung's approval was facilitated by its Knox security platform, which has been deemed secure enough to allow it to be used to send and receive internal emails, and Apple devices running iOS 6 and up are also expected to get the go-ahead for nonclassified communications. So, people of the Pentagon, it looks like it's only a matter of time before you can put down your BB7 handset and pick up a smartphone with a more modern OS.
