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

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

Added (1). I already made a new apple id it still dosn'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?

Make a new apple ID and it should work good luck!

Yes - you'll need an Apple ID to access the App Store to download Apps ~ Link below
