With the iPhone 6 and 6 Plus, Apple finally gave fans what they wanted – an iPhone with a bigger display at 4.7-inches and 5.5-inches respectively. So what’s next for Apple? Move closer to the 6-inch range? Well if rumors are to be believed, Apple might actually be taking a step back and moving towards 4-inch phones again. This is according to an investor’s note issued by analyst Timothy Arcuri of Cowen and Company in which he stated that Apple was working on a 4-inch iPhone that could make its debut in 2015.
