4-inch IPhone 6c. We know that lots of iPhone 5s owners want to buy new iPhone with 4-inch.
"Old" iPhone 5s has very nice unibody, usability and design. But he have "old" hardware.
Today we received one strange message from one Foxconn workers (insiders). He claimed that Foxconn received new 4-inch displays, but not for "old" models. Maybe it isn't iPhone 6c, but other worker from logistic department claimed that in Last October's week, they will have big traffic.
I think this is one the first real message about new 4-inch iPhone 6c, but if it's true, we can see it only in October - November.
