Hot off the heels of the iOS 8.0.2 update, Apple has released the first developer beta of iOS 8.1. The beta build is number 12B401 and presumably focuses on bug fixes and feature improvements to the mobile operating system.
iOS 8.1 beta 1 software is limited to those registered with the official Apple Developer Program. Registered developers can log into the iOS Dev Center and find the appropriate IPSW files to update their test devices with. iOS 8.1 beta will run on all iPhone, iPad, and iPod touch devices that are capable of running iOS 8.
Though anyone can sign up and pay the $99 annual fee to become an iOS developer, the beta builds are notoriously buggy and incomplete, and are not intended for widespread usage outside of app developers and testing purposes.
MacRumors speculates that iOS 8.1 could include support for ApplePay, the NFC-based payments protocol Apple introduced at the iPhone 6 and Apple Watch media event. Apple has said that ApplePay will debut in October.
