Tumpang my question here :-

I have a Payment Question :

Here's my situation I don't have a Credit Card and I asked my dad can I use it & he agrees, but after payment was made by his credit card can I change the information on my iTunes account to none again? Because I registered with a none credit card account. The reason I would like to change it to "NONE" is because privacy. Is it possible?

I haven't bought the Application yet but just need a clarification.

PS : Is the payment procedure & piracy is secure? [Nobody can steal the information of the credit card right?]

M'sia iTunes account, right now I want to buy Monopoly & SimCity Applications. Like i said in the previous post. Can I edit the payment information then purchase & then after purchase can I edit the payment information to none again?

Once if changed to from "None" to Visa/Amex/MasterCard can you revert back to "None" Payment?
