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, CNET reports.

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."

According to earlier rumors, this type of connector is supposedly going to make its way into all of Apple's future mobile devices. While the 30-pin connector is what the iPhone maker has been using for years, a smaller port will create more space in the internal structure of the device.

The latest rumor on the launch of the iPhone 5 is September or October. For the latest iPhone rumors, check out CNET's iPhone 5 rumor roundup.
