This morning, my iPhone 4s took a little swim in a bowl of milk. It was not entirely submerged and was only exposed to the liquid for a couple of seconds. I dried it off and it seemed to be working just fine. WiFi, messaging, and camera seem to have no issue. However, the volume is not working. I can not play music or videos out loud or with headphones in. I also can only hear a phone call when it is on speakerphone. I tried drying it out with a q-tip and blow-drying it for a few minutes at a safe heat & distance. In addition to this, it will not remain off. When I power it down, it goes off and immediately turns back on. The phone is currently hanging out in a bag of uncooked rice. Is there any way to fix this (replacing the headphone jack, etc.), or is my phone done for good?
