An Apple ID is required to set up an iOS device. An Apple ID is used to access the Apple App Store, the iTunes Store, and iCloud. iCloud provides email and the ability to store content on remote servers. The iCloud email is free and comes with remote storage for backups, mail, and documents.

All of the iOS devices, apps, and content are linked to your Apple ID. When an iOS device is turned on for the first time, the Setup Assistant guides you through the process of connecting the device and signing in with or creating an Apple ID. The Setup Assistant also allows you to create an iCloud email account. You can restore settings, content, and apps from a different iOS device from an iCloud backup during the setup process.

If iCloud is not configured during the setup process, use the following path to set it up: Settings > iCloud.

To set up additional email accounts, follow these steps:

Step 1. Select Settings > Mail, Contacts, Calendars > Add Account.

Step 2. Touch the account type.

Step 3. If the account type is not listed, touch Other.

Step 4. Enter the account information.

Step 5. Touch Save.
