In this morning's edition of the Wall Street Journal, a story appeared stating that Apple was working with one or more suppliers to develop different sized screens for prototype devices.
From WSJ.com (subscription maybe required):
"People at Apple's suppliers said it asked for prototype smartphone screens larger than its current iPhone in recent months, and has asked for screen designs for a new tablet measuring slightly less than 13 inches. Whether the designs will make their way to market is unclear, but they could lead to Apple phones and tablets that are larger than the current 4-inch iPhone 5 and 9.7-inch iPad."
Shocker. Is anyone really surprised that Apple is not standing still and working on prototype devices? My guess? This is a "strategic leak" to get the spotlight off of the recent developer portal website hacking.
