I dropped my ipod into the toilet and got it out within about 2 seconds... dried it with a towel, and turned it on. Noticed it was acting weird, and got it in rice. I left it there for the day, and it seemed to work normally except the volume would turn up out of nowhere and the power button wouldn't turn it off... I put it back in the rice for another 24 hours. Then, I used it... worked perfectly. Power button, everything. I plugged it in to charge overnight as usual... in the morning, nothing. It won't turn on anymore... did I ruin it by charging it? The screen shows no water at all... is it just the battery? What now?
