Apple today seeded the second beta of an upcoming iOS 9.3.3 update to public beta testers, one day after seeding the second iOS 9.3.3 beta to developers. iOS 9.3.3 has been in testing since May 23 and comes three weeks after the release of iOS 9.3.2, an update focusing primarily on bug fixes.
Beta testers who have signed up for Apple's beta testing program will receive the iOS 9.3.3 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 OS X betas.
As another minor 9.x.x update, iOS 9.3.3 includes under-the-hood bug fixes and performance improvements to address issues that have been discovered since the release of iOS 9.3.2. No outward-facing changes or immediately apparently bug fixes have been discovered in the first two developer betas of iOS 9.3.3.
