Apple Releases Second iOS 10.2.1 Beta for Public Beta Testers
Apple today seeded the second beta of an upcoming iOS 10.2.1 update to public beta testers for testing purposes, one week after releasing the first iOS 10.2.1 public beta and one day after providing the second beta to developers.
Beta testers who have signed up for Apple's beta testing program will receive the new iOS 10.2.1 beta update over-the-air after installing the proper certificate on their iOS device.
Those who want to be a part of Apple's beta testing program can sign up to participate through the beta testing website, which gives users access to both iOS and macOS Sierra betas. Betas are not stable and include many bugs, so they should be installed on a secondary device.
