Answer 1

I just did this and it worked for me after a frustrating hour (sorry about your 24 hours):
1) Make sure you are using the latest version of iTunes. It can be downloaded free of charge at the Apple website: http://www.apple.com/itunes/download
2) Open iTunes.
3) From the Store menu, choose Sign In.
4) Enter your account name and password then click Sign In.
5) From the Store menu, choose View My Account.
6) On your Apple Account Information page, click Edit Payment Information.
7) On the Edit Payment Information page, select the None radio button to completely remove all your credit card info.
8) Click Done, and then click Done again.
9) From the Store menu, choose Sign Out and then close iTunes completely.
Once you have removed your credit card info, follow these steps:
1) Using your web browser, go to the My Apple ID page at: http://appleid.apple.com/
2) If the site is not displayed in your preferred language, click the Change Language link in the upper-right corner, type the name of your language in the field that appears, then click the Save button.
3) Click the "Manage your account" link.
4) Type your iTunes Store account name (which is your Apple ID) in the Apple ID field, type your password in the password field, then click the Sign In button.
5) Click "Addresses" in the left column.
6) Edit your addresses and make sure the appropriate state is selected for all of them, then click the Save Changes button at the bottom. 7) Next, click "Phone Numbers" in the left column.
7) Ensure your phone numbers are formatted correctly (i.e. the area code is correctly typed into the area code field).
8) Click the Save Changes button.
After you have updated your billing and shipping address, follow these last steps:
1) Open your web browser, and navigate to the Apple Store Online: http://store.apple.com
2) At the main window, choose the option to Review Your Account.
3) Log in with your iTunes Store account name using the same password you use in the iTunes Store.
4) At the Your Account screen, choose the Change Account Information option on that screen.
5) Enter your credit card billing information, including the shipping address information.
6) Choose the proper county for your address. Click continue. Your account will then be updated, and a pre-authorization amount will temporarily be charged to your credit card (which will be automatically removed). Once your account is updated, close your web browser.
7) Launch iTunes. Your iTunes Store account should work normally.
