The new Yelp iPhone app has an easter egg.
Shake your iPhone 3G S three times, and you’ll activate augmented reality mode.
This is the first augmented reality app you can download from the app store, and it may have snuck by because the feature was hidden. I’d download it now in case Apple removes it later!
(Requires the compass in the 3G S to know which direction you’re pointing)
