I can't get my iPhone 4 and my new Macbook air 13" CTO to pair. First off I can se my iPhone on my Macbook but I cant se my Macbook on my iPhone, except when I ask my Macbook to pair with my iPhone. Then I can see it for a short while. When I try to pair it fails. When I set my Macbook to: "use no password" it sais it connects but nothing happens on my iPhone. I just want to connect them so that my Macbook can use my iPhones internet, and connect to iTunes. Hope you can help me.
