How to change credit card info?

[dainla]

I'm new to Windows. When I set up my phone, I signed into my x box account, not realizing all app billing would automatically be going thru the credit card on my x box file.

I'd like to change it. Finding it very difficult to do so. I changed it on x box live but my phone continues to bill the old card.

Annoyed.

Anyone have this problem/solution?

you can do it from your phone as well

when you click on BUY app (int he marketplace of your phone) it sends you to the comfirm page, theres a link you can click that say * change payment option*
