In yet another leaked photo of a possible iPhone 5, a website called iColorOS uploaded an image that appears to give a general breakdown of the new iPhone. The image includes several parts that have been rumoured for the last few months, smaller SIM (again) larger screen and a re-designed antenna to name a few.
In the image above you can see a thin sheet of metal, this is thought to be protective EMI shielding which goes in the back of the handset. The front as you can see is certainly taller than that of the iPhone 4S lending more credence to that possibility of a change in form factor for the iPhone 5.
Apple are thought to announce the new iPhone on September 12th with a rumoured retail date of Sept 23rd in the US.
