Stock Mail Application help

[calamity]

Can anybody tell me how to deactivate a mail account, I tried the google sync method of the google website to sync my calendar on my iphone 3G. However, somewhere along the way something happened and I have not been able to sign in using my password. To make matters worst, I have no way of deleting the mail account.

Settings then mail then accounts then click account and go to bottom there is a delete button

I actually don't have that option under settings. I don't know if it has anything to do with the fact that I have supreme preferences but I cant see it under settings.
