Google Analytics Service -- Drupal Module
Google Analytics now tracks mobile websites and mobile apps so you can better measure your mobile marketing efforts. If you're optimizing content for mobile users and have created a mobile website, Google Analytics can track traffic to your mobile website from all web-enabled devices, whether or not the device runs JavaScript. This is made possible by adding a server side code snippet to your mobile website. Of course, you can still track visits to your regular website coming from high-end, Javascript enabled phones.
