I recently stumble upon one of my favorite forum, the daily mobile and found this interesting free theme named Black iPhone. As you can see from image above, the theme is really nice and as the name shows, it is a dark side of the original iPhone interface. Just so you know, the theme also works on other Nokia touchscreen device, the Nokia N97
