Okay so here's what happened, my iPhone has my dads credit card info on it and I bought too much stuff so he's cancelled the card on my account. Now I can't download ANY free apps or anything because it's making me type in my security code to the credit card when I just want all of the card info off of that account. But I can't just erase it from my phone and I've tried everything. Btw my computers broken so I can't do it from there either. Help please...
