Has Google reviewed the code yet? They just announced a new 2 step process for new Adsense publishers:
Google AdSense announced a new application approval process for new publishers.
The process is now two phased:
(1) Submitting the normal AdSense application
(2) Adding the code to your site and having Google review the code.
Prior all you had to do was be approved on the first step. Now, Google is requiring a second step, reviewing your ad code.
When the ad code is added, the ads will be blank. But “soon after the ad code has been added to the submitted site, a final approval decision will be made and the applicant will be notified by email.”
