iPhone 9 May Be Slightly Thicker Than iPhone 8

In line with earlier predictions from analyst Ming-Chi Kuo, OnLeaks expects the iPhone 9 to resemble the iPhone 8, including a 4.7-inch LCD display with thick bezels, Touch ID home button, and single-lens rear camera, but with a faster A13 chip, 3GB of RAM, and no hardware-based 3D Touch.

OnLeaks also expects the iPhone 9 to be 7.8mm thick, which would be 0.5mm thicker than the iPhone 8. The device will launch by the end of March, starting at around $399, according to Ming-Chi Kuo.

Apple Plans to Switch to Randomized Serial Numbers for Future Products Starting in Late 2020

In an internal memo obtained by MacRumors, Apple has indicated that it plans to update its serial number format to a randomized alphanumeric string for future products starting in late 2020.

Apple says all serial numbers that exist before the change is made will remain the same.

Apple already uses alphanumeric serial numbers, but it has long been possible to determine the date and location that a product was manufactured based on the current format. Readers would often use serial numbers to glean more information about their devices, like the iPhone or MacBook Pro.
