Otterbox has revealed its latest and first ever waterpoof iPhone 4S and iPhone 4 case called the Armor Series case. Otterbox claims the Armor Series case is its toughest case ever built. The Armor Series is completely waterproof, and made from a thermoplastic shell and shock absorbing materials secured by a medical-grade stainless steel latch much like LifeProof's plastic closure latch, that will keep your iPhone protected against water, dust, drops and the unsuspecting threat of being crushed. By the looks of it, it's very bulky indeed. But Otterbox claims all the above is tested to be proof and not simply resistant. Otterbox's Armor Series waterproof iPhone case will be available on June 24.
