Google announced that they are changing the user-agent they use when crawling content for smartphones. It will now be:
Mozilla/5.0 (iPhone; CPU iPhone OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)
Update your tools. Meanwhile it's possible to Fetch as Googlebot in Google Webmaster Tools using the new user-agent string.
In the announcement they mentioned that some site owners were accidentally blocking their content from smartphones with a disallow directive in the robots.txt for googlebot-mobile.
"The new Googlebot for smartphones crawler will follow robots.txt, robots meta tag, and HTTP header directives for Googlebot instead of Googlebot-Mobile," Google noted.
This is supposed to have a very minimal impact across the web, but seems like Google would want to have as many candidates as possible for search results that work well with smartphones.

In addition to responsive design, they provide instruction for how best to configure mobile content when dynamically serving different HTML on the same URL and using separate mobile URLs.
More Smartphone Specific Google Webmaster Tool Insight
Google has also been ramping up smartphone specific insights in their webmaster tools, coming out with mobile specific URL errors in December.
