Several photos were tweeted today by @mornray886 with tag “iPhone 6 #Apple” and have sparked debate in the Apple-loving community.
The MacRumors notes that the pictures they don't have plastic or glass, cutouts for antennas, and in general something is wrong since the FCC text is usually added shortly before the device is released and not on prototypes. Unless the iPhone 6 which is expected to be released in September, is about to be released earlier than the 2014 Autumn.
The other possibility is that Apple could really plan to release the iPhone 6 sooner than usual, possibly in response to Samsung's Galaxy S5 which is expected to announce it at the Mobile World Congress on February 24, 2014 - a month earlier than that the Galaxy S4.
