Just a few months after clearing iOS and Android for military use, the Pentagon has told employees to revert to an older model BlackBerry. While the official reason for this is to give the Defense Information Systems Agency time to install a new $16 million mobile device management system, some defense contractors have said that they suspect the consumer-oriented devices may not meet battlefield security standards.

The Defense Department may not be sold on Android and iOS security. Within months after clearing the mobile platforms for military use, the Pentagon has told employees to put down their beloved iPhones, iPads and Android gadgets and go back to using an older model BlackBerry.
