Nokia is planning to launch its U.S. Windows Phone device in January at the Consumer Electronics Show, WinRumors has learned.

The Finnish handset maker is working with AT&T to launch its Nokia Lumia Windows Phone at the Consumer Electronics Show. Microsoft is planning to support Nokia’s re-entry into the U.S. market with a large presence at CES 2012. Sources familiar with Microsoft’s plans have indicated to WinRumors that Nokia is in talks with several U.S. carriers to provide an LTE compatible handset as its first U.S. Windows Phone device. AT&T is expected to be the primary launch partner of any Nokia Windows Phone devices in the United States. Nokia is also in talks with other U.S. carriers to bring its Windows Phone devices to market on rival networks.

The Verge reported on Thursday that AT&T is a prominent partner of a Nokia Windows Phone launch in the United States. Microsoft is expected to launch its Windows Phone “Tango” operating system update, which includes support for high-speed LTE networks, in early 2012. Andy Lees, president of Microsoft’s Windows Phone Division, revealed in October that Microsoft plans to offer LTE Windows Phones in 2012. Lees revealed that Microsoft is planning to offer LTE Windows Phone handsets in the “not-too-distant future,” during an interview. “The first LTE phones were big and big (users) of the battery, and I think it’s possible to do it in a way that is far more efficient, and that’s what we will be doing,” he added.

The reports back up claims from Windows expert Paul Thurrott that Nokia will launch U.S. versions of its handsets in early 2012. Thurrott discussed Nokia’s plans during his Windows Weekly show with fellow Microsoft reporter Mary Jo Foley on November 3. “I have been told that we expect the Nokia U.S. plans to be announced at CES,” said Thurrott. Nokia is believed to be preparing an “Ace” Windows Phone that is similar to the Lumia 800 but features a 4.3-inch AMOLED display. Specifications of the device leaked in early October.

Windows Phone “Tango”, set to feature on Nokia’s U.S. device, is believed to be an interim release between Windows Phone 7.5 “Mango” and the next-generation of Windows Phone, currently codenamed “Apollo.” Windows Phone build 7.10.8200 was recently discovered in server side logs of a Windows Phone application. A screenshot, believed to be a Tango build, also leaked and demonstrated a new device search feature for Windows Phones. Microsoft’s chasis 2 specifications (Tango) will also include a 480×320 BlackBerry style design and LTE support. The software giant is expected to ship Windows Phone “Apollo” with 1280×720 resolution and dual core CPU support.
