Loud speaker does not work. how can I troubleshoot further? My iPhone 4 suffered water damage where it sat in a puddle of rain water for an hour. I dried it thoroughly in rice for a week but when it was dry, the screen and loudspeaker had stopped working.

I would put the logicboard in IPA, chances are the contact is dirty, IPA is not conductive and removes corrosion

I just thought of something. When the headphones are plugged into the jack, the speakers are disabled. If there is a short somewhere in that jack... well that could disable the speakers. I'll try to remove and replace my headphone jack with another unit and will see if that has any effect. Fingers are crossed! JK

We're in the same boat, Blake. I bought a new headphone jack assembly ($12) on eBay. When it arrives and I install it, I'll report back. I expect this will be my "dead end".

"I had the same speaker issues after my IPhone 4 took a bath in my sink. I noticed that when using the volume switches the OSD told me it is adjusting headphone levels, when no headphones were plugged in. Airplay aswell showed headphones when there were none plugged. I could do calls with headset but no sound came through phonespeaker and loudspeaker. I assumed that ""something"" in the headphone jack ""told"" the phone there was a headset present when it wasn't. So I did a ""deepclean"" of the jack with tissues, toothpick, airblower and hairdryer and you know what: it came back to life!

When I adjust volume levels on my 3GS, it does not say "(headphones)" when no headphones were plugged in. It says "(ringer)". I tried cleaning the jack as you did, haeckmac, but no change. The speakers are still dead. And yes, these speakers are newly removed and replaced, but they still do not work. Thank you for the post/info. I'm glad you got yours back. I am still waiting for my new headphone jack assembly to arrive. Will report back when installed. I'm not as hopeful after reading your experience, however.
