Here is another iPhone 5 rumor from Digitimes and their “upstream sources”. They have changes to the display size and the material used for the back of the iPhone 5.
In addition, iPhone 5′s back design will be changed to a metal chassis instead of reinforced-glasses.
The sources added that the iPhone 5 will adopt a 3.5- to 3.7-inch panel with a design to allow the bezel of the panel to become thinner and make the screen look larger.
The iPhone 5 rumors have been all over the place and we will only know for sure come October.
