The good people at Apple stand by their products, and it shows.  They rarely have problems, and in this most recent test it proves just how durable they actually are.

G-Form is a company that boasts about their protective gear for both sports and electronics.  They conducted one of their "extreme tests" by dropping an iPad from 100,000 feet in their trademark high impact gear.  It survived.

So in another "extreme" test they decided to test their latest product, a cover for the iPhone 4S.  How would you test durability?  By smacking it around like a hockey puck of course.  So they popped an iPhone in the case and took to the ice.  After being smacked at 82 mph, the iPhone came out undamaged.
