As the latest of several waterproof cases recently released for the iPhone 4, InnoPocket’s Amphibian ($30) utilizes a two-in-one design that shifts between everyday use and full-fledged waterproof protection. The base is a clear polycarbonate plastic shell with back, side, and front protection that can be used independently of the waterproof elements: two additional plastic back plates that attach to one another with two screws to form an airtight seal, plus a silicone rubber jacket that covers the face and body of the iPhone 4. Amphibian’s thick silicone sleeve provides full access to the touch screen, although we noticed diminished responsiveness in normal circumstances, and a complete lack of touch response when a standalone screen protector film was already installed on the iPhone 4’s glass face. It should be noted that InnoPocket makes no specific claims as to the waterproof resilience of the Amphibian case,* which is shown being submerged in water, but is apparently not rated for safe use at any particular depth. On the other hand, the company does specifically note that the case is incompatible with the iPhone 4’s rear flash, which might be expected given the low price and simple design.
Updated March 22, 2011: InnoPocket has since noted that the Amphibian has received an IP68 waterproof certification, suitable for 3.6-foot immersion in water, which was received too late to make it onto the packaging or web site.
