iPhone 5 to have flat metal back, larger screen
9to5Mac says a source at Foxconn -- Apple's Shenzhen based manufacturer -- has sneaked them some details about iPhone 5, namely it keeping the same form factor as iPhone 4 but switching the back glass for metal and bumping up the screen size.
Although some reports claim the iPhone 5 will adopt a curved metal back, our source says models have been floating around with a flat metal back. The material of this metal is unspecified. Our brains say aluminum but our hearts wonder if this could be Liquid Metal.
The next major enhancement is said to be a larger display. An enhanced screen for the next-iPhone has been rumored, but an exact screen size has only been pinpointed by Digitimes (4 inches). Our sources do not have precise screen measurements for the iPhone 5 but are certain that it appears to be larger than the one found on the iPhone 4.
An iPhone 4 design with liquid metal backing and 4-inch close-to-Retina Display (it would have to keep the same 960x640 pixel count to maintain app compatibility so the density would go down to below 300ppi) -- sound good?
