Updated 11/14/17: The third iOS 11.2 beta is available to the public, and brings a Wi-Fi/Bluetooth toggle explanation and faster wireless charging.
iOS 11 is the biggest change to Apple’s mobile operating system in years. It’s so ambitious in scope that many of it’s promised features still haven’t shipped yet. iOS 11.1 mostly fixed bugs and brought us a bunch of new emoji, but iOS 11.2 is more substantial, with the addition of Apple Pay Cash. Hopefully, it will also introduce iMessage in iCloud.
