9to5 Mac has a good idea of what the next iPhone will look like. The taller screen makes sense: it allows the device to stay roughly the same size while displaying more information. Most apps should be able to fit this requirement fairly easily, since most apps seem to follow the “toolbar + content” model of Safari, Mail, et. al. Games tend not to, but they should be able to run while floating in the middle of the larger display.
