It was raining alot by my house, and the driveway is kind of crooked so all the collected water leans to one side. My iphone was on my lap and i forgot, so when i stepped out of the car it hit the car door and just ploped into 3-4 in of water. I quickly pulled it out, and i tried to slide it to unlock it but it didnt work!!! So i dried it again and shook it to take out any water that was left in. then it slid to unlock it and it worked!!!!!! I couldnt belive it!!! It is a tank!!
