Despite recent reports that Apple hasn’t finalized the design for its next-generation handset yet, purported ‘iPhone 5‘ part leaks seem to be picking up. We’ve seen home buttons, a SIM tray, and now another one has surfaced.

MacRumors points to a new headphone jack/earpiece/Wi-Fi cable component that recently popped up on Although the piece shows out of stock, the parts vendor claims that it indeed belongs to the iPhone 5…

“If the new part is indeed legitimate, it does represent a significant departure from the component organization in the current iPhone. In the iPhone 4 and 4S, the headphone jack, volume buttons, and mute switch are grouped together on a single component, while the new part associates the headphone jack with the earpiece speaker and Wi-Fi cabling.”

This is actually great news for folks pulling for Apple to release a redesigned handset this fall. In fact, it’s the first purported component we’ve seen thus far that doesn’t look nearly identical to its iPhone 4/4S counterpart.

For those skeptical on the significance of part leaks, keep in mind that similar reports exposed the third-generation iPad’s A5X processor more than a month before Apple unveiled it.
