Apple released iOS 8.1 this morning, after seeding two betas to registered developers. The release adds support for Apple Pay, SMS Relay, Instant Hotspot, iCloud Photo Library, and more.
We’d heard of several issues with Wi-Fi, Bluetooth connections, and iMessage problems in iOS 8.0.2, which iOS 8.1 release notes say have been fixed. There were a number of bugs that were reported by users in iOS 8.0.2, which we hope have been solved in this release too.
I upgraded my iPhone 6 to iOS 8.1 without any issue. Let me know if you’re facing any problems after upgrading to iOS 8.1.
