The first Windows Phone 7 devices to sport CDMA connectivity on board are expected to arrive in the United States in January, most probably announced officially at the CES show in San Francisco.

Microsoft has launched its new mobile operating system on the US market back in November, but it delivered handset sonly for AT&T and T-Mobile.

The other two largest mobile phone carriers in the country, namely Sprint and Verizon, were said to receive their share of Windows Phone 7 at a later time, and it appears that January might be the time frame in the end.

Of course, nothing was confirmed officially for the time being, but rumors on the possible arrival of these devices in early 2011 emerged for quite some time now.

Among them, we can count a HTC 7 Trophy handset, supposedly set to bring the Windows Phone 7 goodness on Verizon's airwaves next year.

Moreover, they should also be the HTC Pro 7, which was announced officially back in October, and which was said at that time to arrive next year on Sprint's CDMA network.

Basically, things seem to have been set when it comes to HTC's Windows phone 7 devices that would offer CDMA connectivity, but nothing is yet known on what other mobile phone makers around the world would have to offer on this.

The Consumer Electronics Show would take place in San Francisco in the beginning of January, and it would make perfect sense for wireless carriers to present there the latest additions to their offerings for the year that starts.

Verizon and Sprint are expected to help Windows Phone 7 sales surge in the United States, though they won't affect the global performance of the mobile operating system that much.

As the guys over at WinRumors state, the launch of CDMA Windows Phone 7 device would be accompanied by the release of the first software update for the mobile platform, set to bring some new features in to the mix.
