Dunno how anyone's going to explain this one. Tucked away on Samsung Mobile Singapore's Facebook page is a smattering of Galaxy S II accessories. And on the desktop dock is none other than an AT&T branded device. That'd make it the rumored Attain. Now before you start screaming that it's just the Infuse 4G and everybody's confused, note that the power button's ever so slightly different than AT&T's current 4.5-inch monster. That said, the power button's also different in a second render of the dock (which looks pretty slick, by the way, with HDMI and 3.5mm jacks). One more pic after the break, and you can check out the whole thing at the source link.
