According to AppleInsider citing Chinese sources, Apple would have started production of the iPhone 5, still set to launch this fall. It would also confirm rumors about the new 16:9 display that would be longer but not wider.
There would be however a difference with what was announced in the multiple rumors concerning this upcoming model, there would be a glass insert in the top back, probably to allow electromagnetic signal to go through the casing and reach the antennas that are now back inside.
This insert would also be the place where the camera and flash are located and tiny holes would conceal the microphone to record the sound while shooting videos.
One question remains however on the CPU (or more exactly SOC) that will power-up this new model. The ongoing trend is now set on more powerful processors with more cores, and Apple could decide to follow that trend by putting a quad-core processor in the iPhone. However, a wiser option would be to keep two cores, to make them slightly more powerful while keeping their power consumption low. After all, even the latest iOS apps still haven't matched the power of the iPhone 4S, which has 'only' 2 cores. Moreover, keeping 2 cores would allow developers to sell Apps that could run on more devices without having to adapt to a new processor.
