Google has launched two new experiments in Webmaster Tools Labs. These are "Fetch as Googlebot-Mobile" and "Create your Sidewiki page owner entry."

"After we launched Fetch as Googlebot, many users with mobile-specific sites asked if we could provide the ability to fetch their pages as Googlebot-Mobile. We thought it was a great idea, and added it as an option to our Fetch as Googlebot feature. We have two mobile options: cHTML (primarily used for Japanese sites), and XHTML/WML," says Webmaster Tools Product Manager Sagar Kamdar.

"After Sidewiki launched webmasters kept asking, ‘How can I put a Sidewiki page owner entry on all pages of my site quickly?’ With the feature that we’re introducing today, you can now create these page owner entries directly within Webmaster Tools for any site you own," says Kamdar.

Google’s Webmaster Tools Labs launched last October. Other tools within it include the original "Fetch as Googlebot" and "Malware details," which provides snippets of code that exist on pages deemed to be malicious by Google.
