I was just going into AdSense for a late night visit to generate some new code, and I discovered that they have launched Google AdSense for Mobile.
Affiliates can paste the AdSense code in the server-side scripting language of their choice into any mobile webpage that complies with Google AdSense program policies.
AdSense for Google only supports the following scripting languages:
PHP v4.3.0 or greater
CGI/Perl v5.8 or greater
JSP v1.2 or greater
ASP v3.0 or greater
There are two Google AdSense Mobile ad formats: single and double; and participating mobile websites must be written in one of the following markup languages: wml (WAP 1.x), xhtml (WAP 2.0), or chtml.
Get details on adding the AdSense code to your mobile webpage.
