A part discovered by French site Nowhereelse may be a section of a next-generation iPhone motherboard used to house the phone's camera and flash. Significantly there are some architectural differences versus the iPhone 5, like the camera and flash being linked together on the same ribbon cable. The part is said to have been obtained by a Japanese vendor, Moumantai, which has also got its hands on other alleged next-gen iPhone components in the past, such as a Home button and a camera lens.
