My iPhone slipped out of the pocket of my rainsuit, landing in a toilet bowl (prior to any activity on my part). I quickly plucked it out, dried and sanitized everything. I'm guessing it was totally submerged for 3 or 4 seconds. It must have bumped the Sleep/Wake button when it went in, because when I pulled it out and looked at the screen it came up with the message "This accessory is not completely compatible with iPhone . . ." The only problem it had was that the Home button would not function. I placed it on the dashboard of my truck, with the defroster running on low heat for about 20 minutes, then let it sit overnight in a barely warm laboratory oven (about 110 degrees F). The next morning, the Home button continued to be finicky, but after a couple more hours, it worked fine and has been fine for almost two months now. Pretty durable sutff, these iPhones.
