While boating to July 4th fireworks, my wife's phone fell into 8 feet of water. My son found it the next day - 14 hours later. Following advice gleaned from this site and the web, we did NOT turn it on. We first removed SIM card, then repeatedly (about 6 or 7 times) vacuumed water out of the SIM slot, plug slot and earphone jack. We then put it in a cotton sock and hung the sock inside our clothes drier by hanging the sock over the door and shutting the door. The phone was suspended in the air and never touched the rotating drum. We laid a folded towel on the floor under the drier door so it the iPhone would not get hurt if we dropped it (we did). We ran the drier on LOW heat (gentle) for 30 minutes, then air fluff (no heat) for the next 30 minutes, repeating this for about 7 hours. We were concerned that this might be too hot, so we switched to using our oven set at temperature of 110 oF. Not all ovens have this low of a temperature, so don't use an oven unless it goes this low. We kept in in the oven overnight and until 6 PM the next day. We then charged it, and it worked perfectly. Amazing!
