Microsoft's Joe Belfiore led the Windows Phone 8 operating system official launch Monday. 

Just five days after the official launch of the Windows Phone 8 operating system, The Wall Street Journal is reporting that Microsoft is testing its own smartphone design with component suppliers in Asia. 

The would-be device seems a further indication that Microsoft is making Apple-like moves to market both its own software and hardware, with the recent Microsoft Surface tablet leading the way. 

The first round of phones with the Windows Phone 8 OS become available this month, including the Windows Phone 8X by HTC, the Samsung ATIV S and the Nokia Lumia 920. The Samsung ATIV Odyssey, announced at the Monday Microsoft event, will be available in December, exclusively through Verizon.
