Some new leaked images claimed to be that of the Nokia Ace 900 Windows Phone have been spotted on a Christmas card distributed by a Microsoft partner.

According to a report by PocketNow, several features suggest that the images are that of Nokia Ace 900 instead of the Nokia Lumia 800. Both the phones are almost identical in design. The pictures show a device with a front-facing camera and a camera button located a bit higher than it is on Lumia 800.

The picture also showed the device with an AT&T logo as well as a 4G logo. This is inline with the reports that AT&T will be launching three new 4G LTE Windows Phones in the coming year.

The software giant has worked throughout the year to improve its operating system for the smartphones. The company had tied up with Nokia to release several devices based on Windows operating system.

Some believe that Windows Phone is emerging as a viable alternative to iPhones and Android smartphones. Microsoft has plans to launch the HTC Radiant and the Samsung Mandel Windows Phone devices on AT&T’s 4G LTE network
