Last week, we shared a pair of photos of Apple's upcoming iPhone 5S, revealing a few details such as a larger-capacity battery and a new dual-LED flash system for the rear camera. At the time, we had some questions about the main chip from the device, which lacked an A-series identification printed on it and which carried date codes indicating that it had been manufactured in October 2012. We have now received several additional photos showing the device in greater detail, with a particular emphasis on the main chip. Prototype iPhone 5S (left) vs. iPhone 5 (right) Click for larger
