Does Icloud of Iphone4 need Apple computer synchronization?

1. First, find the Settings icon on the iPhone home screen, and then click Open.

2. Find the "iCloud" option in the settings list, and then click Enter.

3. Next, enter your own Apple ID. If not, you can click the "Get Apple ID for free" option.

4. After entering the Apple ID and password, click the Login button, as shown.

5. After the system successfully verifies the Apple ID, you will be prompted whether to merge the address book. It is recommended to select the "merge" option, as shown in the figure.

6. Then you will be asked if you want to turn on the "My iPhone has been checked" option. It is strongly recommended to open it, and click OK to continue, as shown in the figure.

Note: Once my iPhone is turned on, even if the iPhone is lost, the password without this Apple ID cannot be used, even if the phone is refreshed.

8. In addition, it should be noted that the free iCloud account has only 5G space by default. Click the "Save and Backup" option at the bottom of iCloud to view the specific space usage, as shown in the figure.
