This is your opportunity to get a glimpse of the future of iOS. Apple just released the very first public beta of iOS 12, the next major version of the operating system for iPhone and iPad. Unlike developer betas, everyone can download it without a $99 developer account. But don’t forget it’s a beta.

The company still plans to release the final version of iOS 12.0 this fall (usually September). But Apple is going to release betas every few weeks over the summer. It’s a good way to fix as many bugs as possible and gather data from a large group of users.
