BBC Video Clicky

I don't own an iPhone but I would be concerned with this. My hands can get very sweaty in winter, yet alone on a hot day, so I would be pretty annoyed if the sensor gave a false positive.

Have you checked your's recently?

Mine are both gone, and my phone has never had any form of substantial contact with water at all. I was refused a repair on that basis, although the issue was somewhat minor so I have survived with it for a fair few months.

It’s the exposed dock connector which lets liquids in - or rather condensation. If that can be plugged up when not needed, the sensors may be less sensitive.

There are two more sensors inside the device. According to Apple all four need to have been triggered to invalidate the warranty.

From what I recall, only two were checked when mine was looked at, the one by the main socket, and one inside the jack socket.

According to the BBC spot on Watchdog last week, the Apple Store people won’t open up iPhones to check them.

Fascinating. They certainly refused to do anything about the problem on the basis of simply looking at those two.

Yes, but according to the official Apple statement on the same program, all four sensors need to have been triggered for a warranty to be invalid.

I guess you've got to stamp your feet a little bit and get talking to the right person in the store. *shrug*
