Long-standing purveyor of rugged mobile device protection technology Otterbox has announced a new series of iPhone 4 and iPhone 4S cases to join its existing Defender, Reflex, Impact and Commuter protective shells. The Otterbox Armor Series iPhone case promises to be its toughest to date and the company confidently state that your iPhone will be protected from drops, dust, crushing and even water. Given the reputation for robustness that Otterbox has achieved thus far, we're inclined to take these claims seriously.
