Government deployment of BlackBerry smartphones in the United States has been big business for struggling Canadian handset maker Research In Motion, but the tide seems to be turning toward Android and iOS. The National Oceanic and Atmospheric Administration said earlier this month that it would be ditching BlackBerry smartphones in favor of Apple’s iPhone, and now the General Services Administration has added the iPhone and Android devices to its list of approved devices. The GSA, an independent 12,635-person agency that procures supplies and products for other federal agencies, spends upwards of $70 billion each year with contracted vendors. In addition to BlackBerry phones, Android devices and iPhones have now been approved for purchase by GSA staff in order to support “applications that can help them work more efficiently with customers like the Departments of Justice and Homeland Security,” a spokesperson told Bloomberg Businessweek. It is not clear when the policy change went into effect.
