Going overboard? Samsung has officially announced a couple of new nature-inspired shades for its ever-so-popular flagship smartphone, the Galaxy S III, bringing the total count of shades to six. Two shades were earlier shown - Garnet Red was an exclusive for AT&T customers since July; Sapphire Black was last seen making its appearance on Samsung's 2012 Olympics Facebook page and UK retailers' webpages. Now, we have Amber Brown and Titanium Grey to ogle at. Unfortunately, it's unclear where or when these colours will be available although Samsung made mention that the shades' availability will depends on different regions and carriers.
