My Iphone 4 won't ring or vibrate
It seems to be stuck in silent mode. The silent switch (on the side of the phone) is turned off with no red showing. I can make and take calls and texts without any problem as long as I see the visual display light up when the call or text comes in. Switching to vibrate doesn't help...it doesn't vibrate either. When I toggle the silent switch up and down, the bell does not appear and the phone does not vibrate. If I push the volume up button on the side, nothing happens. If I push the volume down button, the indicator shows up (I'm currently two marks below full volume). I can play the ringtones in the settings, and I can play music, but the apps are all silent. HELP!
