According to sources, the image above is a part for the iPad 3 that was found on TVC Mall’s website.
The part is apparently a “Microphone Flex Cable Ribbon Replacement for iPad 3″. When compared to the microphone on the iPad 2, it highlights some major design changes due to a different placement:
The new part, when compared with iPad 2, shows a different arrangement in internal circuitry, hinting a major re-design. The tail end of the part makes a “U-turn”, whereas the iPad 2′s Microphone Mic Flex Cable makes almost 90-degree turn both ways. Except for few details, the leaked part so far doesn’t offer a tantalizing tease.
