I purchased app and I am following online tutorial instructions on restrictions. It says to "scroll down" to modify music/movies/tv, etc. I do not have the option to scroll down on my restriction page. I have disabled the safari, you tube and install apps, but can not find "allowed content". I am attempting to install on 2 different Itouchs, but unsure if they are OS 3.x editions. Does this mean my itouches are not the correct version and this app can not be installed? Or is there another way to modify allowed content? Thank you
