LG is increasing the buzz on its 13.4mm thick GD900 handset ahead of the upcoming CTIA Wireless Show 2009. The GD900 which you will recall was first shown at the MWC 2009, Barcelona. Its been said that this time, the 7.2 HSPDA slider with world’s first transparent glass (not plastic folks!) keypad will be functional, running LG’s new S-Class UI on the three inch display. GD900 features a vibrational haptic feedback and the transparent keypad seems to double as a touch-sensitive mouse pad. The GD900 will be available in Europe and Asia in May.
