I wish I had a better story involving wild sex, drugs, or fighting off a home invasion about how my beloved iPhone 4 ended up in a toilet this morning.
Actually...I'd put the phone on some magazines that were headed to the recycling bin. Forgetting where the phone was after, um, I'd done my (stand-up) business, I grabbed the magazines from a counter and heard a highly disturbing splash as the phone hit the water.
Moving as fast as my semi-awake 63 year-old self does that early in the day, I had the phone out of the toilet in just a few seconds.
Luckily, it was snugly enclosed in both an Incipio semi-rigid "bumper" case, and an utrasuede/leather Waterfield slip-in case (highly recommended for slip-in afficionados; great case). So after toweling off the mildly wet iPhone, I decided to turn the phone on and see if it was going to explode in a shower of sparks.
I was pleased to see that the phone worked fine. Seemingly. Except when I fired up my Solitaire app and started to play a game. It worked, but absent the clicking sounds that accompany a card turn. Shit! I thought.
Which turned to double and triple Shit! when I found that You Tube videos played, but with no sound. And I could make a phone call to my wife where she could hear me, but I couldn't hear her through the usual phone speaker -- only when I changed to speakerphone. With earbuds, sound could be heard fine through the headphone jack.
That led me to a panic-stricken Google search.
Where I found "How to fix the iPhone speaker problem (water damage)." The simple advice was to strip some cotton off of the end of q-tips, insert them into the headphone jack, rotate, and remove. I did this several times, with no success (other than getting the headphone jack really clean).
I also read the comments on that post, plus the accompanying You Tube video.
These led me to a couple of other attempted fixes: inserting a credit card in the charging slot at the other end of the phone from the headphone jack, and blow-drying the headphone jack. I also blow-dried the charging slot for good measure.
I don't know what worked, one, some, or all of these fixes. Regardless, after the last blow-drying my iPhone had recovered it's soundability. Bliss! I kept playing my "Brazilian Girls" album to confirm that everything was back to normal.
So give these tips a try if your own iPhone gets wet and refuses to speak to you. The q-tip approach makes sense.
Some commenters on the post surmised that water (a short?) makes the iPhone think headphones are being used, so the external speaker is turned off. I seemed to see a brief message to this effect ("headphones") appear when I started to play "Brazilian Girls" before the phone was back to normal.
If you use a blow dryer, be judicious and don't run it too long.
I left my iPhone on a counter with the dryer on high pointing at it from about six inches way. When I checked back after a few minutes the metal phone casing was really hot. When I tried to turn on the phone, I got a "too hot to use; allow to cool" sort of message. After I waited a while, the iPhone worked normally, so maybe it was the final blow-drying that did it.
Just don't overdo it, or you might have a bigger problem than a speakerless phone -- a cooked phone.
