For over three decades, the Mobile World Congress has become a breeding ground for the latest and greatest in mobile communications. Last year’s MWC showcase welcomed the world’s first 3D smartphone courtesy of the LG Optimus 3D, as well as the highly anticipated Samsung Galaxy S II. The 2012 expo ushered in a new wave of high-tech smartphones that left those in attendance (and watching from home) both amazed and bewildered.
