X1 being shown off at CeBIT following its MWC debut last month is equipped with a particularly curious panel in its software load. Anyone care to take a guess? No cheating and looking at the one we've circled now. Yeah, okay, it's that big AT&T logo front and center, which makes an appearance in several of PHONE Magazine's shots of the interface. We'd like to believe that means that AT&T is a lock to pick up one of the hottest Windows Mobile devices ever manufactured, and indeed, it probably does -- its 3G radio is certainly ripe for the job -- but it's entirely possible to think that Sony Ericsson is still in the process of selling carriers on the device, and is simply trying to get 'em to crack a smile by loading their logo. Keep your fingers crossed, ladies and gentlemen.
