I saw a company at CTIA known as GeveyBox, and they have an iPhone 5 case that is appropriately named The Umbrella. It protects against the aforementioned “big four”, and I will have to say that the man at their booth was very excited about it.
I don’t really have much information about this. I’m not even certain what that cord is in the image. I believe that the Umbrella is entering into a market that is pretty crowded, but the price is nice at about $59.99. You can pre-order it here.
