How do i change my payment methed to none

You can't. iTunes/App Store accounts require a payment method.

If you dont want a credit card on you're account, you can always use an iTunes Gift Card as a payment method.

The 2 answers above are wrong.

In the App Store, tap Featured at bottom left, scroll all the way to bottom then tap on your Apple ID.

Tap View Apple ID.

Enter your Apple ID password when prompted.

Tap Payment Information

Tap None

Thats wierd. I just went to my account settings to see if this was true and saw no option to change the payment option to none. Is it me or are just only some people allowed to select that option?

I do have a gift card balance on my account, so perhaps that is why I'm allowed to and you may not be. I'm just guessing though.
