How to update your device to iOS 8.3 wirelessly Over the Air (OTA)
Ensure your device is fully charged before you begin downloading the iOS 8.3 OTA update as it could take a few minutes up to an hour depending upon the server load and your internet connection speed.

Let iOS automatically search and identify the latest available update for your device and once the update is listed, just hit the Download button. Wait until the download completes and then tap Install button to apply the new update.
You should see a notification once the update is downloaded successfully and ready for installation. At this moment, go to Settings > General > Software Update and then tap Install Now to begin installing the new update.
NOTE: Jailbreakers are advised to follow the iTunes method as OTA updates have known issues with jailbroken iOS devices.
