All signs point to a taller screen for the iPhone 5. For many, that alone will redefine Apple's iconic phone.

Probably more than any other single hardware feature, Retina screens are what consumers of the iPhone and iPad are focusing on these days -- not to mention Apple marketing folks.

And Apple won't disappoint with the iPhone 5. 9to5Mac says the taller screen will boast a resolution of 640-by-1,136. (iPhone 4 and 4S are 640-by-960.)

Those tweaks will yield a resolution "very close to a 16:9 screen ratio, so this means 16:9 videos can play full screen at their native aspect ratio," the Apple enthusiast site said.

A build of iOS 6 for the new iPhone's display may have a home screen with a fifth row of icons and an interface that offers views of more content.
