My iPhone 4 does not ring when I get an incoming call or text MSG. The in app sounds also do not work. They work only with the headset. Music plays and everything else is working fine. Tried restoring, blowing into the jock, pressing near the home button.

Ring/Silent switch on?

Try rapidly plugging and unplugging a headset 10 times to free up a possibly stuck headset mode switch in the jack. If that doesn't help, Restore the phone in iTunes a new phone, without using a backup.

If restoring as new doesn't help, you need to take it to Apple or whoever provides iPhone service in your country.

Have already tried all that 😟

Well... if nothing helps resolve your issue...

Then a Visit to an Apple Store or AASP (Authorized Apple Service Provider) is the Next Step...

Be sure to make an appointment first...

Try to clean the port were you plug the sync cable into the iPhone. That worked for me two weeks ago.
