Apple, you have seriously messed up something here.
I have an appointment with your 'Genius' bar tomorrow
If you tried all of the steps, the final one is to contact Apple, and at least you have done that. They will examine the device and explain your options from there.
Apple is not here on the forum. This is a user to user support forum, and Apple does not participate here, so your statement isn't necessary.
Since you do not indicate what model of the iPhone you are using, one thing that can be said is there is an electrical sensor, and a physical button in the headphone port to detect the headphone being plugged in with the devices that still use the 3.5mm jack. That area can become dirty, depending on the use and environment. That dust, lint, etc. can be forced in further when the headphones are used, and can cause damage to the port area, not allowing the switching out of headphone mode. Those things can happen, and it seems that the use of the lightning port for the headphones in the newer models should eliminate that issue.
