Posting from Las Vegas: On stage at AT&T’s event here just now, HTC CEO Peter Chou detailed plans to offer a new Windows Phone running on AT&T’s LTE network — with a built-in 16 megapixel camera, better than in many standalone consumer cameras.

More details for the camera geeks in the audience: The camera comes with a wide-angle lens, autofocus, dual LED flash, red eye reduction, image stabilization and a backside-illuminated sensor. It also will have a 1.3 megapixel front-facing camera, and will record video in 720p HD.

It’s the type of feature that could help Microsoft stand out as it tries to regain traction against Android and iPhone in the smartphone market. The Titan II will have a 4.7-inch display and run on a 1.5 GHz Snapdragon S2 processor.

Appearing at the AT&T event with Microsoft CEO Steve Ballmer, HTC’s Chou gave Windows Phone a personal endorsement, saying that he uses Windows Phone as his personal device. The statement is notable in part because HTC, an early partner of Microsoft in the mobile industry, has seen its growth fueled in recent years by the success of Android-powered devices.

AT&T isn’t disclosing precisely when the new HTC Titan will be released, other than to say it will be in the coming months. The carrier describes it as the first Windows Phone 7.5 device to run on a 4G LTE network.

Nokia CEO Stephen Elop also appeared at the event, dropping hints about a new Nokia phone, presumably the Lumia 900, slated to be unveiled at his company’s news conference here later this afternoon. Stay tuned for coverage from that event later today.
