The parts suggest that Apple is preparing to have both a black and white model of the so-called "iPhone 5" when it launches as is expected later this year.
The component pictures from "Truesupplier" show a number of other parts claimed to be from the next-generation iPhone, including ribbons and other components.
Apple originally intended to launch a white version of the iPhone 4 alongside the black model in 2010. But issues with paint mixtures led to multiple delays, and the white variant didn't go on sale until this spring.
Pictures of supposed iPhone 5 components continue to trickle in as Apple is believed to be ramping up for mass-production of the next-generation handset. Earlier this month, an alleged iPhone 5 proximity sensor was displayed on an importer site, showing subtle differences from the same iPhone 4 component.
And third-party cases that have proliferated in China have suggested the next iPhone will sport a newly designed exterior. They show a device with curved sides and a flat back, different from the squared off design of the iPhone 4.
iPhone-related rumors this year have been extremely varied, with some claims that the next iPhone will be a minor upgrade to the iPhone 4, while others have suggested it could be a significant revision with a new design and thinner form factor. There have also been conflicting reports on the device's launch, with some expecting the device to debut in September, and others expecting the new hardware to go on sale in October.
