How to download apps on an iPhone 4?

I want to download free apps, but it won't let me because the credit card on my account is deactivated. It always says "sign in required for payment information" or something along those lines, even though the app I'm trying to download is free.

How can I get around this?

You need to log into your itunes account. Even if your card was on. And you tried to buy an app. It would make you approve first.

Hi, I had this problem too when I first got an apple product. You have to include your credit card details or you won't be able to download anything, even free stuff. You just need to include it INCASE you get charged for anything and there's nowhere for the Money to be taken off of. But, if the app is free no money will be taken off your card.

If this is for iTunes the best way is to make a new apple ID and this should sort out the problem
