Apple today began seeding both developers and public beta testers with the fourth build of iOS 10.3 for debugging before an initial release likely sometime next month. This comes a week after the third build became available to the same parties.
The updated build carries over Find My AirPods from the first beta which allows users to locate their lost or stolen AirPods right from the Find My iPhone app alongside a suite a tweaks and bug fixes. If you find something not mentioned here worth noting, email us at firstname.lastname@example.org or hit us up on Twitter @MBEDDEDMaximum.
To install the latest iOS 10.3 beta on your registered device, head over to Settings > General > Software Update. Tap “Download and install” next to the iOS 10.3 Beta 4 listing and you’ll be good to go. I recommend jumping on a Wi-Fi network first alongside plugging in your device beforehand as a) you don’t want data overcharges on your bill and b) you don’t want your phone or tablet to die during the installation process.
