Like Apple and Google, Microsoft collects records of the physical locations of customers who use its mobile operating system.
Windows Phone 7, supported by manufacturers including Dell, HTC, LG, Nokia, and Samsung, transmits to Microsoft a miniature data dump including a unique device ID, details about nearby Wi-Fi networks, and the phone’s GPS-derived exact latitude and longitude.
A Microsoft representative was not immediately able to answer questions that CNET posed this afternoon, including how long the location histories are stored and how frequently the phone’s coordinates are transmitted over the Internet. Windows Phone currently claims about a 6 percent market share but, according to IDC, will capture about 21 percent by 2015 thanks to Microsoft’s partnership with Nokia.
