Choose your input method:
when you click in a type field, email, text, webpage etc, you get a little keyboard symbol appear in the top corner of the screen in the notification bar. Pull this down and click on it and you will be able to select which input method you want to use! select swiftkey, the standard keyboard or any other installed input method here. You used to be able to do it by long pressing the text field, but that no longer works in JellyBean.
