Get Your Login Info Ready
Once the iOS 11.4.1 installation finishes up, your device might prompt you to input your Apple ID/iCloud account details and your passcode.
Most of you should know these but if it's been awhile since you had to login, you'll want to make sure you have the information handy.
There's also a chance some of your apps and services will log you out. If you want to complete the iOS 11.4.1 installation process in the shortest amount of time, make sure you have all of those logins ready.
This way, you'll be able to jump into your most important applications and services for work or school right away.
