About a week since the last beta, Apple is now seeding its second iOS 10.2.1 beta to developers
iOS 10.2.1 beta 2 is now available for download via Apple’s Developer Center. The beta is currently for developers only but we expect it to come out to public beta testers in the next few days.
It is highly unrecommended to run this beta on your daily driver. However, if you find anything new let us know in the comments below!
