The little switch thing on the side of my phone just broke on me and I'm at school. But even when I turn the sound all the way down, you can still hear it. And I can't have the sound going off during my classes. But I don't want to turn my phone off. How do I turn off the sound so its on silent without the little switch on the side of my iPhone?
