One of the most talked-about gadgets at this year's Mobile World Congress in Barcelona was LG's touchscreen Watch Phone, the GD910.
The company first showed a prototype version of the device last year, and in January this year it displayed the finished version at the CES show in Las Vegas. It was not until Monday, however, that LG showed off the Watch Phone's video-calling facility.
The first publicly demonstrated video call on the Watch Phone, which runs a form of Windows Mobile, was made on Monday by LG president and chief executive Dr Skott Ahn.
The "surprise guest" who received the call was Microsoft chief executive Steve Ballmer. An hour after the call, the two executives shared the stage at the launch of Windows Mobile 6.5.
