The small print of a competition organised by Microsoft Canada has revealed the current working names of three new, unannounced future Windows Phone 7.5 Mango handsets--two from Samsung and another one from Microsoft's new best friend Nokia.
The listing, which outlines the rules for a competition in which a variety of Windows Phone 7.5 devices are to be given away, lists a few examples of phones the compo winners may receive, which are currently known as the "Samsung Yukon," the "Samsung Wembley" and the "Nokia Sabre".
The three devices are joined by the only one we've heard of so far--the Nokia Searay. No tech specs or anything else is revealed about the mystery new WP7.5 devices. And the image above is one of Nokia's early WP7 concepts. [WP Central]
