Photos of the iPhone 5S, or perhaps an iPhone 5S prototype, have leaked from the Chinese supply chain. The photos show the back of the device, which is almost identical to the iPhone 5, and also the internals, where a handful of significant changes/upgrades have occurred. Perhaps most importantly, though, these photos seem to confirm that the next iPhone is merely an iteration of the iPhone 5, and not a some crazy, reimagined iPhone 6 phablet as previously rumored.
