Supply Chain Sources Claim Rumors of New 4-Inch iPhone Are False
Feng.com's sources claim the Cupertino company has not placed any orders with its supply chain related to a new 4-inch version of the iPhone for release in 2015. While the iPhone 6 and iPhone 6 Plus have sold well in the few months they've been released to the public, some users continue to prefer the smaller 4-inch display seen on models of the past few years.
