How to download free apps from the App Store on my iPhone 4s? - 1

Every time I try to do it, I put in my apple id and it says this apple Id has not yet been used in the iTunes store and it doesn't download the app. Help please. I already made a new apple id it still doesn't work and it says thesame thing. When i go to review on itunes it shows some billing info. Do i have to fill that out first before being able to download apps?

To be able to download apps you do have to provide a credit card in case you buy something. They don't charge the card for free apps, but they do require the info to activate the account.
