Apple has today seeded the first beta of iOS 9.2.1 to developers. This comes a little over a week after the release of iOS 9.2 to the public. Right now we aren’t sure what’s new with this update. Likely bug fixes and other improvements. Apple usually doesn’t seed updates this small, which means that there’s some major changes that could affect some apps. Once we learn more we’ll be sure to update this post.
Developers can get this beta from the Apple Developer Center. It’s currently not available to public beta testers but it might come soon.
