However, the iPhone 6C was more elusive, as rumors emerged that Apple was working on a "C" model of the iPhone 6 with a 4-inch display, and some rumors even claimed that it was ready for production. But details about its production apparently completely disappeared, and it was claimed that plans for a "C" model was scrapped by Apple.
Few details about the iPhone 6C are available, but we can look to the iPhone 5C, as well as the recently refreshed iPods, for hints.
Sounds like iPhone 6s, 6s Plus, and 6c will all arrive concurrently.
Just like the 5C was essentially an iPhone 5 re-packaged with colorful plastic backs, it's likely that the iPhone 6C will have the same components, specs, and screen size as the iPhone 6. The 5C was also released in conjunction with the iPhone 5S.
In terms of physical design and materials, it's logical that the iPhone 6C would look very similar to the iPhone 6, just like the 5C was similar to the 5. The closest thing to a colorful iPhone 6C is the new iPod touch models that came out a few weeks ago. However, the new iPods have aluminum backs rather than plastic, and it's not clear whether or not Apple will use aluminum or plastic for the 6C.
It seems now that Apple will be releasing two new flagship devices with differing screen sizes every year, as well as a third "C" model every other year from now on. That's a shift from its previous device cycles where the company would only release one device per year.
