Apple’s next-generation iPhone 5S is shaping up to be the biggest “S” upgrade we have seen so far. The iPhone 3GS added faster data and the iPhone 4S improvements were mostly performance-based as well, but Apple seemingly has something bigger in store for the iPhone 5S. BGR recently posted exclusive high-quality photos of various internal iPhone 5S parts and many of them have been redesigned, possibly to make room for new internal components like a fingerprint scanner. Now, new leaked photos published by Letem Svetem Applem show a purported iPhone 5S display next to the current iPhone 5’s panel and there are a number of obvious differences here as well. Apple’s next-generation iPhone 5S is expected to debut next month with a faster processor, an upgraded camera and several other enhancements. The leaked photos follow below.
