the ex-teen idol showed not long ago, is indeed an iPhone 6 Beta sample. The source has apparently been one of Apple's Hong Kong employees, who had been given several such samples for testing purposes.
Jimmy Lin already outed the iPhone 5 two years ago, and that one turned out to be credible, so we have every reason to believe that what he is flaunting at the picture on the right, might indeed be very close to how the final iPhone 6 will look like. Interestingly enough, the Apple insiders from Hong Kong also mentioned to the source the upcoming iPhone will sport a 2K Quad HD resolution display, though it's not entirely clear if they meant the rumored 4.7" or 5.5" one. So far we've been hearing that the 4.7" iPhone 6 will sport a pixel-tripled 960 x 1704 resolution, with pixel density on about the level of the current iPhone 5s, despite the enlarged screen size. In any case, QHD might be just one of the resolution Apple has toyed with in the prototypes or testing samples, so we'll believe the 2K rumor when we see it.
