I have a problem The silent switch is on "silent off" but i still dont have any sound. No keyboard clicks, no text sound and no ringtone. The sound is set to highest, everything is switched to off and it does not say headphones when i set it higher or lower with the side buttons. When i select ringtones / text sound, the sound plays, but when i get a text or a call, Nothing! I tried to restore, but still the same. Anyone have a clue what it could be before i go to apple?
