Hi! So my iPhone got a little bit of water down where it charges with the charger still in it. I was charging for a while, until it started turning the charger on and off (I have no idea how to explain it.. like you know the noise the phone makes when you connect it to the charger? yeah it was making those noises every 2 seconds). So I took the charger out and felt it a bit wet. Right now, it's off, but everything works.. Well, I can call, I can receive calls, but when I lock it there is no sound, when I slide to unlock it there is no sound. I tried playing music from itunes and it didn't work. Although the alarm clock worked. Is this really bad? What should I do?
