What's this? A special announcement from Samsung and AT&T? Whatever could it be? A slim possibility is an AT&T 3G version of the Nexus S. But it's unlikely we'd see an event just for that. A better bet is that we'll finally see the Infuse 4G, that monster 4.5-inch Android 2.2, 1.2GHz device announced way back at CES in early January. Or, it could be something entirely different, altogether. Only one way to find out, of course.
