If you have a website that is optimized for mobile browsers, then you can now make money from your website content. AdSense is now available for mobile phone sites.
To get started:
1) Sign in to your account.
2) Select the AdSense Setup tab and click on AdSense for mobile.
3) Follow the instructions to customize your ad unit for AdSense for mobile.
One restriction: You can have only one ad per page. Still it’s better than nothing.
