We've seen T-Mobile roll out Android 4.0 for its Galaxy S II variant, and now another American carrier is joining the pack. AT&T has started pushing out Android 4.0.3 (no 4.0.4, oddly) to its near-reference version of Samsung's 2011 range leader. We wouldn't brace for any surprises over the conservative OS updates seen elsewhere in the world, but it will at least give you Chrome for Android without turning to custom firmware. The odd man out among the major US carriers is Sprint's Epic 4G Touch -- it's still humming along on 2.3 for now, and neither Sprint nor Samsung has given any further signs that they're ready to make the leap.
Update: A spokesperson tells us that these initial updates are the real deal, but that they're test postings on AT&T's servers before it officially deploys to customers -- you may want to wait before hunting it down. The full-scale rollout is "live very soon," we're told, and customers can check the company blog if there's ever any doubt.
