Vendor SW-BOX.com listed a new headphone jack/earpiece/WiFi cable part, which the site claims comes from the Next Gen iPhone.
In the iPhone 4 and 4S, the headphone jack,volume buttons and mute switches are all joined together for one flex cable, however this new part could indicate that in the next iPhone the headphone jack, ear piece, and WiFi cable will be joined together.
The next Gen iPhone is believed to be set for launch this summer, but it is also rumored that Apple has not yet finalized the next Gen iPhone’s Design.
