How to download iOS 8 / iOS 8.1 and install it on your device the right way:
The recommended way to install a major new iOS 8 update is to clean install it. Restoring your device to a clean install of iOS 8 will help you get the best performance out of your device.
Step 4: Start iTunes. On your Mac, hold the Alt key (on Windows PC, this will be the Shift key), and click on the Restore iPhone… button. iTunes will then allow you to select the .IPSW you downloaded in the previous step. Select it.
Step 5: Now sit back and relax as iTunes installs iOS 8 / 8.1 on your device. This should take a few minutes. Once done, you will be all set to go on iOS 8.
iOS 8 / 8.1 update is also available as an OTA download for supported devices running iOS 7.x or 8.0. Again, before proceeding with the OTA update, you must make a complete backup of your device either via iTunes or via iCloud. Also make sure you have at least 6GB or over free space available on your device to update to iOS 8 if you are updating from 7.x. Much lesser space is needed if you are updating to 8.1 from 8.0. If you plan to update using this method, connect your iOS device to a stable Wi-Fi connection and then simply navigate to Settings > General > Software Update and you’ll be good to go.
