4.6" screen for the iPhone 5?

There has to be an area on the outside where the finger won't overlap onto the screen and register as a touch input. At the minimum. They could get around that now by taking the external antenna and making it extend out past the screen a bit more, but then the device would, by necessity, be wider and you'd effectively have an air bezel where there is a black glass one now. It's not going to happen. Ever. Well maybe when they develop an AI that can reliably detect the difference between a deliberate touch to interact with the screen and a touch that is incidental to holding the device. Maybe the AI will read our minds to know what we meant to do.
