Get caught in the rain and drench your iPhone ? well, then you know things can get a little hinky. But it seems that sweatin? to the oldies with it can also make the phone act erratic, says CNET.
The site picked up an item that ran on KPRC Channel 2 in Houston. The story profiled some exercise enthusiasts who noticed glitches with their iPhones after they worked out. Basically, it's a moisture issue that wreaks havoc, and it's worse with this phone than with other devices.
The problem starts with the sensor. Often times, mobile phone makers put water sensors deep within the phone, like just under the battery compartment and cover plate. Not so with the iPhone. Apple put its ?Liquid Submersion Indicator? at the top and bottom of the 3G handset ? within easy reach of sweaty palms.

Once it goes off, iPhones may experience weird issues like random resets or disabled calling. And let's face it ? calling is pretty much the primary use for a cell phone (or at least for most of them).
Given the number of fitness apps and calorie counters in the App Store, you?d think that the iPhone would be hardy enough to withstand perspiration.
Once tripped, the phones are sometimes impossible to restore to usable condition. All it would take to prevent the problem is a cover plate over the charger/sync port. Sad that the device doesn't come with one. Apparently, the problem's widespread enough that Apple wrote up a knowledge base article about it: iPhone and iPod: Water damage is not covered by warranty.
So consider this a public service announcement: If you work out with an iPhone by your side, make darn sure your hands are dry before handling it. Or better yet, get a protective skin or case for it that covers the bottom of the phone and the headphone jack.
So far I've been using one from Belkin with no problems. But now, I?m thinking of upgrading to a waterproof casing, though I hope it looks better than this one.
