Bought a new IPhone 4 for a relative. I have the same phone. We activated the phone with AT&T, set the phone up with IOS 6.0, etc. Our problem is that the phone has no sound. You can call it and it vibrates, but will not ring. We try to play ringtones, ITunes .... nothing. No sound whatsoever. We have checked settings ... what are we missing in the setup process???? Or do we have a bad phone?? Any help you can provide would be welcome. Thanks.
Did u press the mute button button on the left side? If u didn't try going into settings and go to sound. Then u will see ringers and alerts.. Try to put that into maximum.. Maybe u accidentally lower ur volume
