To download apps, music, books or videos from Apple for your new iPhone, you need to have an iTunes Store account or Apple ID. If you already have an Apple ID from past purchases at the iTunes Store, App Store or Apple Store, you can use the same account to cover your iPhone needs. Otherwise, create a new account, free of charge. Simply provide basic information about yourself, indicate a payment method for future purchases and verify your email address to obtain an iTunes Store account you can use for your iPhone.
Launch iTunes on your computer. The source pane is located on the left and the main pane on the right.
Click "iTunes Store" on the source pane, under "Store." This connects you to the Internet and takes you to the iTunes Store welcome page on the main pane.
Click "Sign In" on the extreme right of the main pane's tab bar. Then select "Create New Account" on the pop-up window. This brings you to a welcome message. Select "Continue."

Verify your email address. Click the "Verify Link" in the message that Apple sends to your email address. This will take you to a "My Apple ID" page.
