Despite the unprecedented success of Apple's iPhone lineup, the company's iPhone 5C seemed like a bad mistake. Apple quickly undid the blunder by discontinuing the "C" series and replacing it with "plus" size iPhones. But rumours have it that Apple is not yet willing to give up on the iPhone C series as it plans to unveil iPhone 6C with a four-inch screen in the first quarter of 2016.

Rumours about the four-inch iPhone have been around for quite some time now. Frequent leaks about the unannounced iPhone 6C have pushed claims of the handset's existence towards legitimacy. According to a new report by GforGames, citing Chinese publication TechWeb, unnamed sources revealed the iPhone 6C would don a more premium look with a metal body instead of the plastic candy-coloured build seen in the iPhone 5C.

In addition, the sources revealed the iPhone would be cheaper than the iPhone 6S and 6S Plus, at about $400-500. At this price, the iPhone 6C is unlikely to pack the rumoured 3D Touch display, seen in the latest iPhones.

The latest report speculating the iPhone 6C features follows another report from last month where key features of the handset were leaked. It is said iPhone 6C would feature an A8 chipset, Bluetooth v4.1, Wi-Fi (802.11ac) and an improved Face-Time (front) camera with f/2.2 aperture, capable of recording HD (720p) resolution video. The handset, being referred to as iPhone 5S Mark II internally, will pack the Touch ID fingerprint scanner and support Apple Pay.

With the iPhone 6C, Apple will break its tradition of launching two iPhones in a year. The iPhone 6C is expected to be released in February, a first for Apple, which  does not release iPhones in the first half of a year.
