We're only about halfway through the iPhone 4S's lifecycle, but speculation about what's in store for the sixth-generation model is already starting to heat up.
The latest comes from a very detailed post by a reader on The Verge. The author says it's possible for Apple to increase the iPhone's screen size to just under four inches without increasing the device's overall footprint. (The iPhone's screen has been 3.5 inches since day one.)

The taller screen would also allow for an extra row of apps on your home screen and make widescreen won't require those annoying black bars at the top and bottom of the picture.
