Although the iPhone registration process can be accomplished through the iTunes application, the device can also be registered at the official Apple site by logging into your Apple account. The Apple Registration page allows you to register any Apple product, and requires the device’s serial number, which is found on the iPhone’s box. Along with the device registration, your account also shows your account history, including previous purchases and current orders, and allows you to edit the payment method linked to your account.

Visit the Apple Product Registration site (see Resources) and click the drop-down menu underneath "Select Your Location".

Click your country from the menu and click the drop-down menu underneath "Select Your Preferred Language". Click your language in the menu.
