Q: Is there a hardware redesign in this generation that could fix this problem?
A: You can go on the web and look at pictures of Nokia phones that ship with stickers on the back that say "don't touch here" -- you can go on YouTube and see these. We should you three phones today, all good phones. So right now the state of the art of the entire industry is that no one has solved this problem. Would I like Apple to be first? Yes. Can we make it better right now? Maybe, we'll see.
I would say, he slipped by this question which leads me to think there is going to be a hardware tweeking sometime in the next few months, if there hasn't been already.
