We’ve seen all kinds of iPhone 5S imagery from backs, fronts, ads and packaging and more.
Today we have a new one. Above, you can see what appears to be a slate/graphite or black iPhone 5S (notice dual Flash) but this one has markings on it including the CCC or China Compulsory Certificate. That means it is headed for the Chinese market which if legitimate would indicate that a Chinese (perhaps China Telecom?) version of the iPhone 5S is imminent.
It could also indicate that the Slate iPhone 5S isn’t just a prototype color as we’d originally considered.
Recently Barclay’s issued a report postulating that iPhone 5C would be the Chinese iPhone. This would seem to indicate that China will also see iPhone 5S.
