The latest update to the Yelp application for the iPhone and iPod touch sports a hidden augmented feature, called Monocle, for iPhone 3GS users.
The hidden feature, which is activated by shaking the device three times, allows 3GS users to see nearby Yelp-reviewed restaurants overlaid on video of the user’s surroundings, showing the aggregate rating, type of cuisine, and pricing scale information, if available.
Yelp for the iPhone and iPod touch is available now as a free download from the App Store; continue reading for screenshots of the feature in use.
