Update: The original source, Nowherelse, posted an update with new information regarding the leaked dock connector images claiming the connector has 16 pins, eight on each side, with eight likely being reserved for future uses:
We have obtained new information about this connector. We have indeed learned that it is not equipped with 8 to 16 pins but distinct functions or 8 on each side thereof to note that one of them would have no basis of record and would be for possible future use.
Update: iFixit told MacRumors that the metal frame counts as its own pin even though there are eight gold pins. This adds up to nine pins, as we reported the other day based on iOS 6 source code, and this may mean these above photos are legitimate.
Also: We cannot help but notice that these images are akin to some MicroSD cards (image via).
