The Baltimore Sun has regurgitated a recent Apple patent filing for a 3D, multitouch, zooming user interface. So the speculation jumps immediately to iTablet/iSlate and iPhone 4.0? Is this the "surprising interaction method" we'd heard rumored? Or just another in a long list of patents Apple may or may not ever get around to implementing in a real device? Place your bets in the comments!
