(Telecompaper) BlackBerry has reported revenue of USD 1.6 billion for the second quarter ending 31 August, down 49 percent from USD 3.1 billion in Q1 and down 45 percent from USD 2.9 billion in the year-earlier quarter. The revenue breakdown for the quarter was around 49 percent for hardware, 46 percent for service and 5 percent for software and other revenue. In the second quarter, BlackBerry recognised hardware revenue on around 3.7 million smartphones. Most of the units recognised are BlackBerry 7 devices, part because certain BlackBerry 10 devices that were shipped in Q2 will not be recognized until those devices are sold through to end customers. During the quarter, around 5.9 million BlackBerry smartphones were sold through to end customers.
