AllThingsD is betting on the launch of new iPhone on the 10th September based on their source. So far, no one knows what Apple is up to. What had been rumored are iPhone 5C, iPhone 5s or iPhone Lite.
I think it might not be a surprise if Apple decided to showcase a premium and bigger screen version of iPhone and a budget version that is colorful and cheaper for the developing countries.
Also, we might be hearing fingerprint sensor too.
