Apple has today seeded the second beta of iOS 10.3 to developers. We see this update two weeks after the initial release. In this version of iOS we find a new feature that will allow you to locate a lost EarPod, tweaked app opening/closing animations, a new, more secure file system, new popups for asking to review an app, and more.
To get this version developers can go to Settings and find it under Software updates. If you aren’t testing this version of iOS yet you will need to go to the Apple Developer center and install the profile.
