Heeft geantwoord op: Why aren't my ring tones working on my iPhone 4?my iPhone 4s volume goes on and off. 1 minute its working the next minute its not. This cheap old phone. I should have got an iPhone up to date. But I was being stupid and cheap. Now look what I'm going through. I cant even listen to music and on top of that my mute button doesn't work. Can anything else go wrong. Oh yeah my phone has a crack in it.
