XDA Developers is reporting that Samsung have ditched approximately 600,000 rear casings for the phone and that they are retooling the production process. The white version is reportedly OK, and will still be hitting shelves and hands across the world.
Just when I thought I'd be able to buy one of each color when I'm in Taipei for Computex. Samsung, you disappoint. Looks like it's two of the white-colored versions now!
