We’re not sure if the phone mentioned in this article is the Nokia “SeaRay” or the recently leaked by Microsoft “Sabre”, but apparently a certain Nokia Windows Phone was briefly displayer on posters over at T-Mobile Germany’s own shop at the corporate headquarters in Bonn, Germany.

The picture shows off T-Mobile pre-installed applications like Mediencenter and Top Apps but the tag on the right gives away a 3.7-inch AMOLED display that is convex, Windows Phone 7.5 and what appears to be Nokia’s own “Drive Safely to your Destination”, a 3D satellite navigation system pre-installed. Aside from the AMOLED screen, the phone is rumored to sport a microSIM card slot (a la iPhone 4) and to be unveiled at Nokia World 2011 conference in London at the end of the month.
