An 4 inch phone (iPhone 6 mini) would be nice.
But what really would interest me is a 3.5 inch phone (iPhone 6 nano). The original iPhone was released nearly 10 years ago. Imagine what you could do with modern technology. The screen is credit card sized.. and if they reduced the bezel the phone wouldn't be much bigger. Perhaps no bezel - edge-to-edge screen. A phone that you could slip into your wallet. That would fit into a tiny handbag. Or jeans pocket. Perfect for kids too. It would look cute.
