According to a report in the Korean publication ET News, the next iPhone will be incredibly thin at just 6 millimeters. The iPhone 5S is currently 7.6 millimeters thick, which is still thinner than many other top-tier smartphones. ET News is calling the next iPhone the iPhone Air, but it's probably a bit too early to start speculating on names right now.
One reason the next iPhone could be so thin is because it's also said to have a larger screen that would allow some more space for internal components. Analyst Ming-Chi Kuo, who has an amazing track record predicting Apple gadgets ahead of time, says the new phone will have a nearly 5-inch screen.
Apple is on an annual release schedule with its iPhones, so don't expect a new one until September at the earliest.
