It has been rumored for past one year that Apple will replace the 30-pin dock used by all iOS devices for charging and syncing with a smaller “Mini” dock. And since the images of iPhone 5 back cover have leaked this mini dock rumor have gotten even stronger. Today, TechCrunch posted they have confirmed from various sources that Apple will indeed use a smaller 19-Pin “Mini” connector. John Biggs wrote on TechCrunch:

Although the form factor and actual size are still unknown, TechCrunch has independently verified that Apple is working on adding a 19-pin port, replacing the current 30-pin port, to the new iPhone. It is a move that will surly send shocks through the iPhone accessory ecosystem.

The new port is similar in size to the Thunderbolt port available on many MacBook devices but I’ve been told by three independent manufacturers that the pin-out will be different.
