Currently Being ModeratedApr 6, 2009 8:56 PM (in response to SoCalSkippy)So After reading all this "fixes" none of them worked.
What I did was get someone to call you turn speaker mode on and off a couple of times, leave speaker mode on, and hang up. this worked for me.
Hope it all goes well.MacBook Pro, Mac OS X (10.5.6)
Currently Being ModeratedApr 14, 2009 5:19 PM (in response to SoCalSkippy)After about an hour of fiddling with headphone jacks, blowing and cleaning with cotton buds, playing music then unplugging etc. what finally worked was simply calling the iPhone from another phone. The ringtone sounded, I answered and could hear through the earpiece again.iPhone 3G, Mac OS X (10.5.6)
Currently Being ModeratedApr 25, 2009 10:58 PM (in response to shorty_jr)i tried putting headphones in 50+ times and it did not work,i think i may have had a drop of rain go into the earphone jack.
After getting annoyed and trying heaps of different thing i eventually put my mouth over the headphone jack and sucked as hard as i could and that fixed it......
Currently Being ModeratedMay 5, 2009 10:35 PM (in response to bigdalla)I was laughing so loud when i read this, but I tried it anyway since unpluggin and pluggin the headphones didn't work for me. Guess what? Your suggestion worked!!!!! Thank you soooo muchDell XPS 410, Windows XP

Currently Being ModeratedMay 27, 2009 8:04 PM (in response to SoCalSkippy)My iphone headphone jack isn't working. Its as if the phone is thinking that opposite. When there are no headphones in I can't hear anything and pressing the volume button shows (headphones)on the screen. However when the headphones are in it acts as if there are none in it and all the sound functions work fine.
I also know that it definitaly thinks that is in headphone mode when nothing is plugged in as while playing music and putting the headphones in but not all the way you can get music to play through the headphones..
I have just recently swapped the back case on my iphone and it came with headphone jack switches etc already in place. All I had to do was attach a cable..
Do you think that there is anyway to get a program to manually change it or a command line that will reverse it?iPhone 2G
Currently Being ModeratedJun 23, 2009 9:04 PM (in response to bigdalla)This problem happened to me a few weeks ago and I tried everythiing in the first two pages of this thread. And I mean everything. I eventually got it to work after doing the complete reset, which changes settings. loses icon positions, etc. A real pain. I live on the Gulf Coast ( Pensacola ) and things are very hot and humid, I keep the iPhone in my shirt breast pocket and when I had the problem I had been outside and my shirt was wet with perspiration.
Anyway, it got fixed and the phone was fine for these three or so weeks.
Today we had the first big rainstorm in some time. I got home, plugged the phone into the charger cable, and was reading in bed when I got a call, and no sound. Looked closely and it was in headphone mode. I definitely did not want to go the reset restore whatever again and came back to this thread.
Read the post about sucking on the headphone receptacle (and it made perfect sense) and pulled one slower half-lung capacity draw and touched the volume control and it had switched from Ringer (headphone) to Ringer. As I was watching it switched back to Ringer (headphone). I then did a longer and stronger pull and it switched back to Ringer. I gave it a couple more pulls for good measure and it's working fine.
Never in the most recent cycle had I used earphones they had not been near my iPhone for a week.
I think there may be more than one reason that this happens, but moisture on the inside of the headphone jack (and not necessarily in the ID of the barrel) apparently gives enough conduction to make the iPhone think that the earphone are plugged in.
Being inside with cool dry air conditioning is the first step, sucking that air from the charger connector through the iPhone apparently dries condensation and the conduction path goes away.
Some of the other "fixes" may just be spending time inside in dry air and whatever you were doing when the conductive path dried up is credited with the fix. Including putting the plug in and out from 7 to 9 to 50 times.
Blowing in dry air or sucking dry air through the iPhone (in a dry air environment) and out the headphone jack should be the first thing you should try. Don't blow your water vapor rich exhalation into the headphone jack (obviously)
I can see iPhone carrying tourists/conventioneering visitors to New Orleans in the hotel lobbies sucking on their iPhones after a hot afternoon rainstorm. The warm moist air gets into the iPhone, they go into an air conditioned lobby and the inside of the headphone jack cools, makes condensation happen where the warm moist air still is (inside the iPhone) around the connections in the wall and on the outside of the connector barrel and they are stuck in headphone mode.
But because they have read these posts about sucking the jack, that's what happens. What a sight.

Currently Being ModeratedJun 27, 2009 5:36 PM (in response to SoCalSkippy)ok I admit.... I was lauhing at the sucking thing..
I tried sucking thru the earphones jack with no luck..
tried it thru the iphone connector.. oh ho... the "earphones" word disappeared but still no sound..
tried it again thru the speaker outlets and oh miracle it came back
Thanks for the tips guys!!!
Currently Being ModeratedJul 15, 2009 2:23 PM (in response to SoCalSkippy)I -at least temporarily- fixed the problem by spraying a little 'Kontakt Chemie 60', then using a can of compressed air (also called 'Duster') and inserting/removing the headphones repeatedly. Would recommend holding your iPhone upside down to not leak
The first minute or so after spraying Kontakt 60 the iPhone did not even detect when the headphones were plugged in. Which is to be expected when putting a liquid with a reductant in there. Cleaned off leaking drops Kontakt 60 with tissue, cleaned of the headphone plug after each removal.
Bonus: Now I don't hear any crackle when I turn the headphone in the jack
Previously had just tried with compressed air, and well that didn't help. I'll how this works out. Else I'll have to replace the headphone jack á €49 and a couple of days (or in warranty and a couple of weeks). Reading on electronics fora I really ought to now put a little 'Kontakt 61' (I don't have that here) sealant in the jack to stop corrosion, but -there's always a negative- that would make dust stick in there even more.. Don't think that is advised.MacBook C2D 2GHz 4GB & Mac Mini 1.25GHz 1GB, Mac OS X (10.5.7), iPhone OS 3.0
Currently Being ModeratedJul 28, 2009 10:51 AM (in response to bigbillpns)My theory is that it is a simple case of the phone overheating as in my case, it only seems to occur after prolonged use or in hot environments. I tested my theory as follows: I placed my phone between my hands or between my legs for about ten minutes to heat it up. I then entered the number pad in the phone mode and punch a few numbers to see if I could hear anything (an easy way to test to see if you can hear anything coming from the speakers). Nothing. I then blew cold air into the headphone jack and a few second later...sound came back. I did the test a second time and, again, the sound failed to come through the speakers when the phone was heated up. Blew cold air through the jack and, presto, the sound comes back. I'd be interested to see if anyone else can recreate this problem like I can. If this is the case, then the various solutions being proposed (q-tip cleaning, inserting and removing the headphone jack several times, etc.) are merely helping to cool down the unit and have nothing to do with removing debris from the jack. I suspect Apple is aware that this is the problem and simply cannot afford to admit to it.iMac, MacBook Pro, Mac OS X (10.5.5)
Currently Being ModeratedJul 28, 2009 4:18 PM (in response to awillimd)It's either a software issue or the headphone jack needs to be replaced. I got my iPhone fixed at a repair store in Dallas called Dr. Cell Phone. A couple of people on this message board referred me to them. When I went to the store, they mentioned they also take care of software issues. Seeing how this is probably a software issue (or a problem with the headphone jack) you should give these guys a call. That way you can diagnose the problem. Here's the link:
