There are two ways to upgrade the iOS on your device:
Upgrade on your device directly via Wi-Fi
- Open the Settings – General – Software Update.
- Wait for your device to check for updates. When it finds an available update, tap Install Update
- Wait for the update to download and install. Don’t do anything with your phone while it does.
We suggest you connect your device to power since it may run out the battery during update. When you see the message "Your software is up to date", the upgrade should be done.
Upgrade iOS through computer via iTunes
- Connect your iOS device to your Mac or Windows PC and open iTunes.
- Go to "Summary" tab and click "Check for Update" button
- Wait for the update to download and, when finished, confirm you want to install it. Wait for the update to install.
Your device may reboot several times during the update. After update, you need to do a primary configuration for your iOS 6 device. If you encounter any errors when update, please directly start over the upgrade process.
