Rumors leaked last month that the iPhone 5 will have a new Dock connector with only 19 pins, as opposed to the rectangular 30-pin port found on the mobile today.
This rumor is said to be confirmed today by TechCrunch, which wrote that three independent manufacturers affirmed that the 19-pin port is in the works.
"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," the tech news site writes.
In addition to TechCrunch's confirmation from manufacturers, the Web site MobileFun shows sketches of the new iPhone case, which displays a much smaller dock connector "similar in size to micro USB."
CNET contacted Apple for comment on the size of the new dock connector. We'll update the story when we get more information.
