Help needed! My iphone suddenly turned to "headphone mode". After using the headphone for several phone calls and listen to songs, I unpluged the headphone from the iphone and later I realized that when I called out or call came in, I can't hear the other party's voice, he can't hear me too.

I called out the ipod, picked a song to play but no sound coming out from the bottom speaker. I pressed the volume buttons (the side button), the speaker sign appeared with word "headphone" or "ringer (headphone)" on top of it - eventhough the headphone not plugged in. (photos attached)

I thought my firmware corrupted and I re-installed 1.1.4 but the problem still there. Could it be the mechanical fault ? Now I can only make/receive calls either with the headphone or bluetooth or handsfree/speaker mode.

Has anyone come across this ? Please help. Thanks.

Just logged in and glad to see some many replies, thanks and appreciate.

I have done all resets but didn't work. Reloaded the firmware 1.1.4 to my phone, jailbroke/unlocked with Ziphone (sorry, frozzbyte - not due to Ziphone) and still it won't work.

I think it should be more to a "mechanical fault" and I followed zc_squash's advice and link to a site. The trick is to plug-in and out using the headphone jack in order to remove the debris. A respondent reported that the method works but I tried several time, still not working. Maybe I need to wait for few days, carry the iphone around hopefully that the "debris" will fall/disappear but itself.

nokia2003, I don't mind to be "ajak-ed" out for coffee but I am from Penang...

Anyway, thanks again guys for your advice.

Added on July 13, 2008, 3:10 pmI solved it! After plugged-in and out (fast in and out) a few times and blow air (using my mouth - not airgun), it's back to normal.

I am not the only one got it, try visit this site and many reported of such case, hope it helps.
