Who’s serving the Lynx ad? It’s not iAd, but it’s iAd-ish in that it pulls up an in-app browser panel to display an interactive, iAd-like webpage, with a spinning carousel and all.

Update: Kept reloading and finally got a traditional text banner, which said “Ads by AdMob”, so presumably the Lynx ad was also provided by them as well. Didn’t know Google was trying to copy Apple.
