Via Seattle Weekly:
Guys, last night I did that thing where I dropped my phone in the toilet, and it wouldn’t even turn on afterwards. I was at Video Isle whining about how I was going to have to buy a completely new iPhone, and there was a man there who just happened to work for AT&T. I asked him if I should try to blow-dry my phone, and he said:
SAVIOR FROM AT&T: Turn it off completely, put it in a bag of rice, and leave it there for a couple hours. The rice will absorb the moisture.
ME: *Blank stare*
S.F.A.T.&T.: Just do it.
So, I went home, got out a bag of rice, and stuck my phone in there. I took it out about an hour later, tried to turn it on, and the screen kind of lamely flickered at me. But at least it was turning on, so I stuck it back in there. A couple hours later, before I was about to go to sleep, I took it out and turned it on…AND IT TOTALLY WORKED.
Good tip, as water damage voids the iPhone’s warranty.
