Obviously, with a story like this, we suggest that you keep a cynical eye when you view the pictures. The cut out for the home button does not appeared to be centered which actually could have allowed someone to obtain a discarded panel, or it could be indicative of a fake. And the bezels could have been scraped off.
Considering the number of leaks we saw last year prior to the unveiling of the Apple iPhone 5s and Apple iPhone 5c, we also should not dismiss the legitimacy of the panel so quickly. Compared with the panel for previous iPhones, you can see the larger screen and how the bezel work contributes to it.
The latest speculation is that Apple could be moving up the introduction of the Apple iPhone 6 to July. And there is still the matter of that rumored iPhone phablet with a 5.5 inch screen.
