Google Notebook was one of the few Google apps that we're not available from a mobile phone. Now you can go to http://google.com/notebook/m and find a HTML version of Google Notebook optimized for mobile phones. There's also a new notebook "Mobile notes" where you can add notes directly from the homepage.

The "Unfiled" notebook is a great way to access your bookmarks, but you can't add a new one from the mobile interface. Other limitations: there's no search option, you can't edit notes, add labels or change the settings.
