It's not just TV and cinemas that are getting the 3D bug, mobile phones are too, with HTC looking to be first to market with a 3D mobile phone.By that it's referring to an Android smartphone featuring a full 3D screen, which means those 3D hollywood blockbusters could be available in the palm of your hand. That's the theory anyway.According to 3Dradar, HTC has previously demonstrated 3D mobiles at the Mobile World Congress in Barcelona back in February of this year, primarily to show the prowess of its mobile chips. Next year's event could see a finished 3D phone in display, with 'insiders' claiming a 3D Android superphone will hit the shelves before the end of 2011.Whether that will be accompanied by any 3D mobile content isn't clear. Like 3D TVs, the hardware will always suffer if the content isn't readily available - especially if there's a premium price to pay. There's been no official announcement as yet, but HTC has recently been advertising for a 'display and camera design engineer', that has 'familiary with 3D display and imaging technologies' and with 'multiple display technologies (TFT-LCD, PMOLED, AMOLED, E-ink, etc).' So you suspect plans are certainly afoot.Expect more on this during the next Mobile World Congress in Barcelona, hopefully with a handset showing us 3D in action on that 3D-friendly screen. We'll lay down good money Avatar is showing off on it.
