So, For some reason or another itunes/app store took out my ccv code on my credit card (the three digit number on the back) and it is now telling me the code is invalid and its not... And it wont let me download any apps from the app store, including ones i've already paid for..This wouldnt be a problem except for the face i just had to do a restore and now am back at zero.. Any ideas on how to fix this? Someone told me i can use my paypal account instead but I dont know where/how to change it... Thanks
