Get Your Login Info Ready
You'll want to have your Apple ID handy when you start the download process because Apple might ask you for it during the iOS 9.3.5 installation.
Most of you will know your login and password but if you haven't logged in in awhile, you'll want to track that info down before you make your move.
You'll also need the passcode of the device. This won't matter for many people but if you're installing iOS 9.3.5 for someone else, make sure you get that code before the person leaves the device in your hands.
In addition, make sure you know all of your login information for the various apps and services you have on your phone or tablet.
There's a chance the iOS 9.3.5 update will log you out of those forcing you to log back in. Now would be a great time to ensure that you know all of your login credentials.
