The image below is a fan made concept design of what is being called the iPhone SJ (Steve Jobs). It is similar in design to the iPhone 4S with the metal band around the edges but is thinner and has a larger screen.
The rendering shows all the buttons in the usual places. This design wont be the iPhone 5 of course as concepts often are not too close to the real thing, but we expect a slightly thinner device with some design tweaks. The creator Antonio De Rosa comments that his version (not real of course), has a 10 megapixel camera and an A6 processor.
