When I bought my $20.00 gift card, it didn't work for the iPod Touch 2.0 software upgrade. So, I contacted Apple and they told me that if I get a credit card, I keep to keep my $20.00 and I get the update free, which was quite nice. Anyway, now that I have a credit card number stored into my files, it's there. I cleared my payment information and now, whenever I click to buy Super Monkey Ball, it says it'll go into my credit card, which I DO NOT want. Help?
