Moment just got a whole lot less interesting, didn't it? What you're looking at is allegedly Samsung's Galaxy S Pro for Sprint, a potential blockbuster of a phone that's said to have WiMAX support and a front-facing cam -- basically, the QWERTY answer to the EVO 4G (and this one's presumably got a Super AMOLED display, to boot). It doesn't look exactly like a standard Galaxy S with a keyboard grafted on, so we're not sure how confident we are that the "Galaxy S Pro" name is going to stick by the time it hits retail -- but you could call it "ball of dung" and we suspect it'd still sell like hotcakes. Stay tuned for more on this one as we get it.
Update: Android Community has more pictures posted now that confirm both the Galaxy S branding and the 4G radio (note the "Sprint 4G" logo on back). Thanks, Linh P.!
