Google extends support for determining links to your site

This is a huge improvement over the 'link:' operator in a standard Google search. Google will now show every internal and external link to each page that Google has indexed. This is not only amazing, as no other tool offers this kind of information, but extremely useful.

Want a list of every URL that is linking to your website and what page(s) they are linking to? You can do this by choosing the Download all external links option at the bottom of the report.

The one thing I wish they would add is the ability to sort the results based link quantity.

Check it out in the new webmaster tools:
