Nokia will have touch-screen mobile phones in the future--that much we know from its announcement recently about S60 (Symbian Series60) handsets supporting touch-sensitive displays. What is less known, however, is that the Finnish giant had filed patent documents for such phones dating back to May 2006.
In the document discovered by Unwired View on the U.S. Patent and Trademark Office site, Nokia envisioned a device with two screens to display different kinds of information depending on the angle at which the clamshell is opened. Control of the device is possible using either the buttons or the display.
