AppleiPhoneSchool.com If you're looking for extreme protection for your iPhone then look to the Otterbox for iPhone Armor Series. This case is truly water proof up to a depth of 3 feet. Not only is it waterproof but it's dustproof, dirtproof, sandproof and dropproof. Here I'm testing the black version but there is also a yellow and black version similar to the Otterbox Defender Series. If you're going for looks, this case isn't for you. It is bulky, but for the type of environment this would be used in, looks probably don't matter much. The following video includes an underwater test. AppleiPhoneSchool.com
