The Microsoft (NASDAQ:MSFT) smartphone rumor refuses to go away. Though a company exec denied the rumor in June and suggested Microsoft won't compete with Windows Phone partners such as Nokia (NYSE:NOK), BGR reports a "trusted source" indicates Redmond is working on a high-end smartphone, with a launch expected in the coming months. A Chinese site recently claimed Microsoft's phone will be sold under the Surface brand, and be available in 1H13.
