Default Re: 9780 trackpad fixed by OS update?

I've managed to reproduce the problem by putting into a ziplock bag, breathing into the bag to make the air moist, sealing the bag, and putting it in the fridge (not the freezer) for 10 minutes.

When I took it out, the trackpad wouldn't work at all for about 10 minutes, then it came good. I think this phone has some corrosion that causes the trackpad circuit to short out when there's even slight condensation on it.

I tried the same test on another phone, and it was fine, although I wonder if you could wreck a phone by doing this for too long.

The faulty phone is a "new" warranty replacement, so I suspect it's a refurbished phone with a problem they didn't detect.
