Is this a joke? Nope. Apple released an app that does nothing but feature iAds. I normally love just about everything Apple does, but this just seems downright tacky.

I imagine Apple wanted to release 'iAds Gallery' (lets you browse ads) on April 1st, but the review team delayed it.
You can take a gander at this sad little app here.
