Commuter Series saved my iPhone 4 from 3 flights of stairsRead Article
The building I used to work in was three stories tall and I would often take the stairs. One day I was emailing while walking down the stairs on the third floor, tripped a little and dropped my iPhone. To my surprise it did not immediately stop where it fell, but kept on falling- almost like when you place a slinky on the edge of the stairs. I started chasing it down the stairs, knowing that I would probably be picking up the remains of my iPhone piece by piece. When I finally caught up to it at the bottom of the stairs, to my complete surprise my iPhone was completely fine.
Not even so much as an extra scratch on it- thanks of course to the OtterBox.
