Apple has today released iOS 10.0.3. This is a minor update that brings some bug fixes. Mainly we see a fix where some users lost cellular connectivity temporarily. This version comes about a month after releasing the last update.
To get iOS 10.0.3, users can go to Settings > General > Software update > iOS 10.0.3. You can also manually download the update within iTunes. It’s a fairly small file and shouldn’t take long to download. Install times will vary based on your device.
