Microsoft provided details at the Mobile World Congress.
Meanwhile, Nokia (NOK) is launching three Android phones even though the company's handset unit is being sold to Microsoft and the latter is looking to facilitate cheaper Windows phones. The Nokia X will cost €89 and will integrate Microsoft services such as Bing and Skype. The home screen will use tiles, as in Windows phones. Meanwhile, the Nokia X+ is priced at €99 and the XL, with a bigger screen, at €109.
