So, I've used the same debit card on iTunes for years. Last week, I accidentally overcharged it. Once I had put more money in my account, it said I had put in the wrong security code and stopped working. The other day, I gave my dad my old iPod Touch (the least I could do for giving me an iPad!), and the first credit card he used for iTunes had the same problem, and he's got good credit. Last week, I bought one too many Lady Gaga albums on iTunes and it said my security code is incorrect. Has anyone else been having these problems? What gives?
