I'm trying to help my friend out with his iPhone. Basically he has added a pre-paid visa card to his itunes account, it worked fine however he no longer has this card so wants to remove it. I just cant see an option to do this, ive read a fair few tutorials online which all appear to say he should be able to remove it at this screen here by selecting none. Basically he has £15 on his itunes account, however because he has a card associated with his account it will not let him spend this £15, or remove the card Ive not really used iTunes so if im missing the obvious do point it out! however i have looked in just about every menu possible and really dont see any way to remove a card, or to just use the £15 on the account instead.
