Apple today seeded the first beta of iOS 10.3.3 to developers. We see this one day after the launch of iOS 10.3.2. Right now we’re unsure what’s new in this version. It’s a minor update, so we’re guessing it contains nothing big.
To get this version developers with the beta testing profile installed can go to Settings > General > Software updates > iOS 10.3.3. If you don’t have the testing profile installed yet, you can download it from the developer center.
