Windows Phone 7, Microsoft's latest mobile operating system, is expected to receive a major software update later during the ongoing year, one that would be codenamed “Mango,” and which might have been just spotted in a video on the web.

In all fairness, the video does not focus on the Mango update specifically, but a device that appears in the clip at a certain moment seems to sport certain graphical elements that hint at the said software.

The video can be seen embedded at the bottom of this article, offering an overview of the newly released NoDo software update, the one that brings copy&paste into the mix, in addition to a range of other enhancements.

At the 2:47-2:48 mark, a second device that appears in the image shows on the front a new search button, one that was not present in the initial Windows Phone 7 release, or in the new NoDo software update.

According to some of the latest reports around the Internet, Microsoft is already testing the Mango update internally, though in its early stages, and the said button might be part of the update.

On the other hand, this button might point a new version of the browser that could be added to Windows Phone 7 before the Mango update arrives, namely Internet Explorer 9 (IE9).

This is one of the enhancements that Windows Phone 7 is set to receive this year, and some suggested that it might be released on handsets before the said software update arrives.

Since the mobile browser would definitely come with Bing integration, the search button that can be seen in the video and in the photo attached to this article, would point more towards the arrival of IE9 than towards Mango, provided that the former won't be included in the latter.

When available on Windows Phone 7, Internet Explorer 9 would bring support for HTML 5 and Silverlight, the Trident rendering engine, and gesture support for mobile phone users.
