Why not see who's advertising around the advertising coverage while you're at it?
Yelp sneaks in a little iPhone AR
Published on .
Augmented Reality wasn't supposed to officially come to the iPhone until its launch of OS 3.1, but Yelp sped things up and introduced it in an easter egg within its own iPhone app. To unlock the feature, users must launch the Yelp app in an iPhone 3GS and give the phone a few good shakes. Once activated, users can point their iPhone cameras to any street and Monocle will overlay information on nearby restaurants.
