Dickson told Reuters he has five to 10 sources in China who buy Apple prototype parts directly from factory-line workers, which are then sold from $250 to $500.
Sonny Dickson, who lives with his parents in suburban Melbourne, attracted attention in August after he released detailed pictures and videos of the new grey and champagne casing on the upcoming iPhone.
On Thursday, Dickson leaked what he says are the first detailed pictures of the new model's new "home" button with its rumored biometric fingerprint scanner.
"While the design differences have yet to be technically assessed, they could have a whole lot to do with the rumored biometric fingerprint scanner that numerous pundits and analysts have predicted. In fact, we'd count on it," Dickson said on his website, sonnydickson.com/
Apple, which zealously controls information of its new product launches in the face of rampant interest from consumers, has invited media to an event on September 10, where it is expected to unveil at least one new model iPhone.
Supply chain sources told Reuters in June that Apple is expected to launch two new models this year, one with new fingerprint technology and a cheaper version in a plastic casing, widely referred to as the iPhone 5S and iPhone 5C respectively.
Apple plans to dress up the 5C model in a range of five or six colors to differentiate it from the more expensive model that has traditionally come only in black and white, according to the sources.
Apple declined to comment on Dickson's actions, and he says they have never contacted him about it.
