So you always have your contacts' most up-to-date information when and where you need it.When you turn on i Cloud Contacts, all of the information stored on separate devices uploads to i Cloud.You can change your Apple ID from your account page or from your i OS device with 10.3 or later. On your i Phone, i Pad, or i Pod touch: Go to Settings After you enter the email address that you want to use as your Apple ID, a verification code is sent to you at that address.From your Apple ID account page: Go to appleid.and sign in. Enter the verification code from the email into the fields provided and start using your updated Apple ID. You can change your Apple ID to any other email address you control, as long as it's not already in use as an Apple ID.Using multiple Apple IDs might be confusing and cause issues with accessing purchased content or using some services.But if you already have different Apple IDs that you want to use with i Cloud and the i Tunes & App Stores, follow these steps.If you want to change your sign-in preferences later—for example, use a different Apple ID for i Cloud and i Tunes—you can go to your device Settings or System Preferences.When you sign in to the i Tunes & App Store for the first time, you might need to add a credit card or other payment information to help secure your account.
If you change your payment method, make sure that your account information matches the credit card information on file with your financial institution.You can’t sign in to the i Tunes & App Stores with more than one Apple ID at the same time, or update the content you buy with a different Apple ID.We recommend that you use the same Apple ID for all Apple services on your device—including the i Tunes & App Stores and i Cloud.You can find and edit your contacts on i or in i Cloud for Windows.Any changes that you make automatically update on your other devices.
If you turn off i Cloud Contacts, your information won't automatically move from i Cloud back to your device.
