Larger display

The Home button is still there, the grid screen of app icons, and the curved corners of earlier iPhones. But it looks odd - the proportions are different, as though it's been stretched like a piece of toffee. The display, for the first time, has been increased from the 3.5in diagonal measurement of earlier models. This one is 4in, but as the phone is the same width as before, it just looks strangely enlongated. Front on, that's the only visual difference, except the glass frame that protruded from the metal band is replaced by an aluminium bezel with chamfered edges, Apple points out.
