Research In Motion has announced that US Department of Defense (DoD) had approved six models of the company's BlackBerry 7 for use on its networks, extending a long relationship with the smartphone known for its tight security.
Scott Totzke, RIM, said, “Security was crucial for some government and corporate customers. Leveraging the full power of BlackBerry smartphones is also important as it helps them realize the full potential of their investment in the BlackBerry platform."
