In late July, Reuters reported that new iPhone would feature a 19-pin dock connector. Then last week iLounge issued a report saying the dock connector would have just 8 pins.
Today, 9to5Mac says they've found references in iOS 6 that seem to indicate it will actually be a 9-pin connector.
We discovered a possible reference to a 9-pin dock connector in the iOS 6 beta. The reference comes as a new iOS hardware feature called "9Pin," so we're assuming this has to do with the dock connector. Obviously, there is no way to be 100% about this.
Notably, the reference is in a part of the OS that details general hardware features for iOS devices. This is taken to mean that Apple will be implementing the smaller connector for than just the iPhone.
