According to Businessweek, Nokia is expected to announce a partnership with Microsoft this week, which will put the Windows Phone 7 mobile OS on future Nokia devices. Nokia CEO Stephen Elop basically said this was going to happen in his memo, and from the looks of it he's wasting no time making it happen.

Nokia also talked with Google CEO Eric Schmidt about the possiblility of putting Android on Nokia phones, but those dealings fell through. (Sidenote: GOD DAMMIT.) Both companies hope the partnership will help them get back into the game against the likes of smartphone hardware and software makers such as Apple, Google, Samsung and HTC. Businessweek expects Elop to make this announcement tomorrow. [Businessweek]
