Just curious but what protection does a bumper offer? My wife just dropped her iPhone breaking it. This is forcing me to buy her the new iPhone4. She did not have her phone in her case for some reason shattering the glass and breaking the phone. So I am on a search for a case of some sort for her new phone. Both she and I are minimalist and the bumper is appealing but am having a hard time seeing the value of protection with it. Thought?
