Apple on Wednesday posted the first beta of iOS 9.2.1, an update to the recently-released iOS 9.2, which came out just over a week ago. At present, little is known about what improvements, security measures, and bug fixes are contained in the new beta, which is currently only available to registered developer accounts (a "public" beta will likely be released within the next 24 hours or so). The new beta is likely to focus on enhancements and further fixes for flaws found in iOS 9.2.
