Apple has released a fresh second beta version of iOS 9.2.1 for iPhone, iPad, and iPod touch. The new build arrives as 13D14 and is available now for users participating in the developer beta and public beta programs.
Those who would like to install iOS 9.2.1 beta 2 can do so through the software update mechanism on their compatible devices running the prior iOS 9.2.1 beta.
If you’re not currently running a beta build but would like to try it out, any user can enroll to participate int he iOS Public Beta program, though it’s not particularly recommended as beta software is notoriously more problematic than stable releases. Additionally, users in the Apple developer program can find the appropriate versions for their device on the Apple iOS Developer Center website. Always back up a device before attempting to install beta software on it, and ideally do not install beta system software onto a primary device as it may become less reliable.
No specific features or changes are expected in iOS 9.2.1, suggesting the release will primarily focus on bug fixes and improvements to the mobile operating system.
