Should we trust this mockup? Nothing is official until the very last day, but it definitely makes sense for Apple to make its new iPhone appear similar to its current tablets. You can clearly see how the device even uses the same distinct, elongated volume buttons.
What’s very strange (and we are fairly certain won’t happen) is the single LED flash for the camera on the back. It would simply make no sense for Apple to have adopted a dual-LED flash in the iPhone 5s, and then, to switch back to a single-LED flash the next year.
For all else, this is just a dummy claiming to stem from insider information, and as good as it looks to you, don’t forget to look at it with the usual grain of salt at hand.
