How to find your device model number




To find your device model number, you can either look at the back of your device or go to Settings > General > About and tap on Model. The model number will start with an "A" followed by four digits. You can compare your model number with the list above to see if your device is compatible with iOS 8.


Back up your device before updating




Before you update to iOS 8, you should back up your device to avoid losing any important data or settings. You can back up your device using iCloud or iTunes. iCloud backs up your data wirelessly and automatically when your device is connected to Wi-Fi and plugged into a power source. iTunes backs up your data when you connect your device to your computer and sync it with iTunes. You can choose either method depending on your preference and available storage space.


How to back up using iCloud




To back up using iCloud, follow these steps:


  • Make sure that your device is connected to a Wi-Fi network.



  • Go to Settings > iCloud > Backup and turn on iCloud Backup if it is not already on.



  • Tap on Back Up Now and wait for the backup to complete.



  • You can check the progress and confirm the backup by going to Settings > iCloud > Storage > Manage Storage and selecting your device.



  • You can also see when the last backup was done by going to Settings > iCloud > Backup.

  • Make sure that you have the latest version of iTunes installed on your computer.



  • Connect your device to your computer using the USB cable.



  • Open iTunes and select your device from the upper-left corner of the screen.



  • In the Summary tab, click on Back Up Now under the Backups section.



  • You can check the progress and confirm the backup by going to iTunes > Preferences > Devices and looking for your device's name and the date and time of the backup.



  • You can also encrypt your backup by selecting Encrypt iPhone/iPad backup and entering a password. This will protect your backup from unauthorized access and also include your passwords, health data, and HomeKit data in the backup.



Update your device wirelessly or using your computer




Once you have backed up your device, you are ready to update to iOS 8. You can update your device wirelessly or using your computer. Wireless updates are convenient and do not require a computer or a cable. However, they may take longer and use more battery power than updates using a computer. Computer updates are faster and more reliable, but they require a computer and a cable. You can choose either method depending on your preference and availability of resources.


How to update wirelessly




To update wirelessly, follow these steps:


Turn on automatic updates




If you want your device to automatically download and install iOS 8 when it is available, you can turn on automatic updates by going to Settings > General > Software Update > Automatic Updates and toggling it on. This will allow your device to download the update overnight when it is connected to Wi-Fi and power. However, you will still need to manually confirm the installation of the update when prompted.


Update manually




If you want to manually check for and install iOS 8, you can do so by following these steps:


  • Make sure that your device is connected to a Wi-Fi network and has at least 50% battery charge or is plugged into a power source.



  • Go to Settings > General > Software Update and tap on Download and Install if iOS 8 is available.



  • Agree to the terms and conditions and enter your passcode if required.



  • Wait for the download and installation to complete. Your device may restart several times during the process.



  • You can check the progress and status of the update by going to Settings > General > Software Update.



Troubleshoot common issues




If you encounter any issues while updating wirelessly, such as insufficient storage space, slow download speed, or error messages, you can try these solutions:


  • Free up some storage space on your device by deleting unwanted apps, photos, videos, or other files. You can also use iCloud or iTunes to back up and remove some data from your device.



  • Restart your device and your Wi-Fi router and try again.



  • Update your device using your computer instead of wirelessly.



  • Contact Apple support or visit an Apple store for further assistance.
