The rumors have been hot and heavy that the iPhone 5 will have a 4-inch screen (compared to the current 3.5 inches). And the big question was how Apple would accomplish that, with the latest round of rumors saying the current prototypes simply add pixels to the height, while keeping the width the same. The result is that in landscape mode you end up with a 16:9 aspect ratio, just like the widescreen shape of an HDTV. So now the speculation is how that space will be used. Again, Rene Ritchie of iMore has an excellent analysis of the options -- and what it all means. He includes very helpful mockups of these options, giving you a clear picture of how a wideiscreen will alter your user experience.
