In my case I own an Iphone. I DO NOW WANT to give Apple my credit card numbers and whatsoever, that's why I prefer use Itunes card. In these days I'm getting tired of the continuos restrictions they put on the Iphone. So when I'm gonna change my cell, I would certainly change to android (Galaxy Samsung series). But then I will be oblidged to give Amazon, Paypal or whoever they are my credit card numbers. Can there be another option similar to Itunes card for android devices?
