If the ‘x’ does not show, it means that you have only preinstalled apps (calendar, contacts, weather, etc.). the x only shows up for applications that you, yourself, explicitly installed (as per AppStore). Also, when icons go wobbly, you can move them around, like to the next page or in and out of the bottom bar.
