Blue for me and my 4-year old
My 4-year old son uses my iPhone 4 as much if not more than me. We are both ardent supporters of the West Virginia University Mountaineers - the primary thing my son does is watch YouTube basketball highlight videos so that he can practice on his hoop in the living room. Given our mutual love of the Mountaineers, we are constantly on the lookout for blue and gold everything - His head might explode if dad's phone was magically turned blue . . .
