It seem in fact Apple did not pull the iPhone porn app from the iTunes store but rather the makers did “…because of high demand…”

The lead developer Allen the Geek, writes on its site:

The Hottest Girls app is temporarily sold out. The server usage is extremely high because of the popularity of this app. Thus, by not distributing the app, we can prevent our servers from crashing. Those who already have the app will still be able to use our app. To answer the question on everyone’s mind: Yes, the topless images will still be there when it is sold again. -ATG dev team

So the iPhone porn app was not pulled by apple, just temporarily “Sold Out” because of problems from the image servers. Other porn apps are still available, get ‘em while there hot!
