In case this is hard to visualize, iLounge went the extra mile to illustrate it. "Our artist's rendition provides a rough idea of what this change will look like; it echoes the current-generation iMac design, to be sure." To be sure it does, approximately, as . 

"The change in height will include a lengthening of the prior 3.5" screen to roughly 4" on the diagonal," Horwitz continues, piling on those details. "As the new iPhone won't widen, this appears to confirm that Apple will change the new iPhone's aspect ratio for the first time since the original iPhone was introduced in 2007, adding additional pixels to the top and bottom of the screen. A change of this sort took place between the fourth and fifth generations of the iPod nano, but didn't impact any third-party software. This obviously will."

Yes it will. No question. If the aspect ratio actually did change. This issue has been debated for at least the last 12 months, and Horwitz doesn't add much to it, or elaborate on it, or bother to describe just what the impact would be.

The best recent treatment of this topic, , expands on an idea originally suggested by a caller to the weekly Vergecast: if Apple changes the iPhone aspect ratio from the current 4:3 to 9:5. The result would be a screen that's longer but not wider, moving from a 3.5-inch to a 4.0-inch diagonal, preserving the Retina Display pixel density, and offering more room for apps without requiring changes to the apps.

Horwitz also says the Next iPhone will have a new, smaller Dock Connector on the bottom of the phone.
