It looks like Sony Ericsson’s new flagship device will be known as the Sony Ericsson Arc HD, aka the Nozomi. A couple of photos of Sony’s first dual-core device have emerged, as well as a Quadrant benchmark. The specs that are expected for the Arc HD include a 1.5GHz dual-core processor, 4.3” 1280 x 720 display and 1GB RAM. As has been the case with Sony’s 2011 Arc Range, it looks like the Arc HD will come with a rather sleek form factor. The leaked handset that has been pictured over the web is running Android 2.3 Gingerbread, but given the rate at which Sony has kept its handsets updated this year, it wouldn’t be all that surprising if the Arc HD is running Ice Cream Sandwich by the time it’s released.
