Lin has posted the images on the Chinese micro-blogging site Weibo.
In the pictures, he appears holding an iPhone that looks larger than the current iPhone 4S model.
“Today I can confirm that the upcoming iPhone 5 will be longer and will have aluminum back like the iPad. With its four-inch screen and thin body it feels about the same in the hand [as iPhone 4S did]. The iPhone 5 doesn’t use the standard 30-pin dock connector; instead Apple put a smaller 19-pin connector,” Lin wrote in a post on his blog, as reported by The Next Web.
The site wrote that there are some ‘irregularities’ in the pics and that Lin’s device is actually a high-end fake or an early manufacturing prototype.
Several photos show Lin using the device and display it from various angles.
The iPhone 5 is rumored to be launching on 12th September at an Apple live keynote.
