Creating apple id in iphone 4s without credit card?

I can't create my apple id without credit card. There are lots of blogs and videos on internet telling how to create it without credit card. All tell to select none in the option where it requires to select payment option. But I can't find this option in my cell. I think this option is not available now. Is this possible now to create one? If yes; then how?

You go to the app store and download a free app. Then it will ask you for an apple id, you have to create one. It will say a credit card or none.
