IPhone 4 symbols

There is an official manual and it's a good place to start as about all the features are listed there (see page 17 and page 31; Portrait Orientation lock ... Page 194 for the sounds, ringers, vibrate features):

Check the volume switch on your husband's phone to see if it is set to silent/vibrate.  Look on the left side of the phone if you are facing it.  There is a switch; if you see an orange indicator, the phone is set to silent.  Flip the switch to turn the sound back on.

I have tried everything...the ringtones aren't working...i tunes..you just can't hear any sounds..other than vibrate.

Thank you! I tried that too hon..the switch is on correctly.

Every iPhone has the manual right in Safari.

Just go to the root of Safari's bookmarks and there is the manual in easy to access categories.

Thank you, I had forgotton about safari.  I remember that now.  I looked all thru the manual..couldn't solve volume prob.

If you plug in headphones, do you hear volume then?

Do you perhaps have a bluetooth headset connected?  When wired or wireless headphones are connected, the majority of the audio is piped to the headphones.

I don't have the headphones plugged in....but you are right,,when I plug the headphones in I hear the volume.  I can call the phone and hear it ring with the headphones on.  So how do I turn off the headphones?  Thank you so much!
