Here are the new emoji characters that are available in iOS 6

  The long list of changes made by Apple in its new iOS 6 is completed today with one new set of emoji characters that until now were unavailable to users. By default, these characters are not displayed on your keyboard, but you can activate them by going to the menu Settings>General>Keyboard>Add New Keyboard>Emoji. After installing this keyboard, go to an application that allows you to enter text and press the button that displays a globe several times until you see the new characters.

  Using the same method you can display the Emoji characters that are available in iOS 5.
