A Windows Phone 7 user has filed a lawsuit against Microsoft claiming that the software maker collects data from mobile phone users without their knowledge. The lawsuit also contends that Microsoft misled Congress this year when it said that it did not collect data without their permission. Microsoft admitted that it “collects limited information necessary to determine the approximate location of a device” But added that “collection is always with the express consent of the user and the goal of our collection is never to track where a specific device has been or is going””]
