You do know that this whole problem goes away with a proper 301 to one or the other, correct? (Pick one, with www or without.) If you can access your site via www and without www, as far as search results go, you're basically dividing the strength among the two domains.

Otherwise, can't you just reset it without deleting it? You just need to specify the domain, I think. This

domain=.mydomain.com;

sets it for mydomain.com, www.mydomain.com, sales.mydomain.com, products.mydomain.com . . . if you want to keep www and not domain,

domain=www.mydomain.com;

if you want to keep non www and kill www,

domain=mydomain.com;

At least, I'd give it a try.
