So I have been loving my iPhone 5 since day 1. But just today I got a phone call from a friend. I picked up and didn't hear anything. This guy has an old broken Sprint Android phone that gets terrible reception, so I figure it is a problem on his end. I try to call back, but I hear no ringing. I restart my phone and try calling again. No ringing. Texting works, data works. Tried calling other numbers, the phone calls go through but my phone does not put out or send any sound. System sounds like alarms work, keyboard clicks, game sounds, music playback, etc, all work. I tried plugging in my ear pods - no luck. Tried in my car connected to my bluetooth stereo. No ringing. Note - this was on a "perfect" iPhone 5. No issues so far, phone calls worked up until today. Has anyone else had this issue? I am trying a restore right now and have a genius bar appointment for tomorrow.
