Sony Ericsson‘s upcoming Xperia Arc is surely making waves these days. The 4.2 incher will come with Android Gingerbread and will be available in black and silver. The device looks really slick and sexy and comes with Sony Mobile BRAVIA Engine display. Sony Ericsson has not kept the Timescape and Mediascape UI and has rather scaled them down to mere widgets, making the UI snappier. Check out the video below for a preview of the device.
