I just got an itouch and i want to add apps. I went to the app store and get the ones that are free. I tried to install it but it says i have to log into my apple id account. But it said i didn't review my apple id account on itunes. So i did it and i got to the part where it said 'Billing Information'. And its telling me to give them the credit card numbers and monthly bills. If i write down everything do i have to pay for getting the free apps?
