How do I correct my billing info to download apps on the app store?
I'm on the road and I'm trying to get Facebook mobile on here. I try to download and it says to go to billing info. The app is free. Every time I enter the security ode it shows up in red letters at the top that it's a invalid pin. How do I correct this from my phone to download stuff again?
iPhone 4S, iOS 5.1.1, Security code invalid for billing
