Change the Information in Your Apple Account

You can change your billing address, switch the credit card you have on file for Store purchases, or edit other information in your Apple Account without calling Apple. Just launch iTunes, click the Store icon in the Source list, and then sign in to your account by clicking the Sign In button in the upper-right corner of the screen.
