For all-day, take-anywhere protection of your iPhone 4S or 4, the green Lifeproof iPhone Case for the iPhone 4S/4 makes a great choice. The case has a full IP-68 rating against water and dust, and is designed according to military specifications. It will guard against shocks and impacts to your phone, and remains fully sealed against minute dust particles. You can even take it underwater during trips to the beach or pool. While offering unsurpassed protection, the case itself only adds a scant 1/6" to your phone, so it won't add much bulk when you're carrying it around.
You can feel free to continue using the built-in camera on your iPhone as well -- the case has double AR-coated optical glass lenses for unprecedented crystal-clear photo and video quality. Plus, you can benefit from access to all phone features while it's inside the case. The case also improves the bass and mid-frequency speaker response by utilizing the back of the case as a sub-woofer for a richer, fuller sound. To sweeten the deal, Lifeproof has included a bonus headphone adapter and keeper for the headphone jack cover along with this rugged case.
