In the latest iPhone refresh, a lot changed. In addition to the screen size uptick, the overall design of the phones changed, bringing a more well-rounded (punny!) form factor, and slipping us away form the squared-off design of iPhones past. Still, one thing remained unanswered: how would Apple treat the smaller iPhones moving forward? The iPhone 5C is near its end of cycle, and the iPhone 5S will likely disappear next year. A new rumor suggests Apple is going to come back strong with a new 4-inch phone to replace them.
