LG is showing at the CTIA 2009 its GD900 slider mobile phone that has transparent keypad and S-Class UI. The GD900, as previewed at the MWC 2009, is probably the world’s first phone to feature a transparent glass keypad, which serves as a touch-sensitive touch-pad.
The LG GD900 has a 3-inch display and a main camera and secondary camera. It supports HSDPA 7.2Mbps network.
