Many sources have been suggesting the that the touchscreen phone Morgan Freeman(Lucius Fox) uses in the Dark Knight Batman movie is the Nokia Tube. However, Nokia was quoted in Crunch Gear stating:
In the summer blockbuster, The Dark Knight, a Nokia device is
prominently featured. We worked closely with the producers of The Dark
Knight to develop an appropriate device that would suit the
technology-savvy character of Batman. The Nokia device used in the film
is not a commercial product - at this point.
Nokia does offer through Verizon the Nokia 6205 The Dark Knight
edition mobile phone with a special JOKER code to get exclusive content and win prizes. Of course, there is mobile Dark Knight Game in which the JOKER terrorizes GOTHAM.
Who knows what Nokia has up their mobile sleeves. We'll see in the next Batman movie....
