I updated the Mowser WordPress Mobile plugin that Russ posted a while ago and added in an admin page where you can configure your AdMob site ID without having to go in and poke at the code. I was considering going back and updating the WordPress Mobile with Style version that I had as well, but there are some other mobile WordPress plugins floating around already. I’m going to have to poke around and see what the state of the others is before I go and hack mine up some more.
