The latest iPhone 6C rumor says the phone will be 4-inches, include a metal casing, and be available next year. Analysts with Jefferies put together the latest iPhone 6C report and the firm has described the device as being an "extended" version of the iPhone 5S. Jefferies believes the usual iPhone style will be used on the 6C.

An industry survey was used for the report. Jefferies paid attention to Apple suppliers and members of the industry in order to figure out what Apple is likely to do with the handset. No leaks provided the firm with the information.

Economic Daily, a Chinese news site, also said this month that AU Optronics is working on 4-inch screens for the iPhone.
