Undoubtedly the iPhone 5 (or whatever they market it as) is already under heavy development. After Steve fired the last lot of RF engineers he needs to get people on board who understand function as much as design... You can just imagine the next WWDC. Steve makes a 3G call to Jonnie Ive. "Isnt it magical? I'm actually talking to someone over a mobile network while holding the phone in my hand!". Apple reinvent the phone. Again.
