Apple is reportedly planning to return to the 4-inch form factor next year with its next iPhone 6S mini smartphone.
Analyst Timothy Arcuri of Cowen and Company claims it's “possible” the company may release three versions of the iPhone including an iPhone 6S mini with a 4-inch display. The analyst further claims the phone will be similar to the iPhone 5S launched last year. But, the phone will sport a new design, curved edges, similar to the current iPhone 6 and iPhone 6 Plus. Arcuri claims the "iPhone 6s mini" may feature "purpose-built low cost components" from Qualcomm to ensure the price down.
