Q: Why is there a message saying, "This Apple ID has not yet been used in the itunes store"

Hi midanjm,

This prompt is usually displayed when your Apple ID needs to be configured for purchases. We'll need to run through the additional steps to setup your country, and payment information. See Step 10 and above on this resource (For iPhone, iPad, or iPod touch):

iTunes: How to set up an Apple ID within iTunes

Tip: If you are trying to create an account using an existing Apple ID, like your iCloud email address, you will receive a prompt telling you that your email address is already an Apple ID. Simply tap Continue, and then tap Use Existing Account on the following screen.

 

- Next, you'll be required to enter your billing information. To choose a different Credit Card type, tap one of the available options, and then tap Done. You will not be charged until you make a purchase.

 

- Once you've filled out all of the fields for your billing information, tap Next.
