Yelp was featured prominently in iOS 6 by way of the new Siri features announced at WWDC, but rumor has it that the review network's integration won't end there. Documents recently issued to developers show that there will be a Yelp check-in option through Apple's new iOS 6 Maps app.
TomTom is providing the lion's share of mapping data in iOS 6, and though they have their own points of interest database, Yelp seems to have taken the reins for ratings, reviews, and photos of businesses. While Yelp is a great pick for those things, checking-in and social sharing isn't really what Yelp is best known for. If Apple had extended their newfangled Facebook partnership to have some kind of check-in through maps, it might be a bigger deal. Likewise if they integrated Foursquare or even rolled their own check-in solution for hundreds of millions of iOS users.
Of course, iOS 6 is still in beta, so we may see something like that before the iPhone 5 launch in the fall.
Neither Apple nor Yelp have otherwise confirmed the functionality.
How many of you use Yelp? Would a check-in option be remotely useful to you as part of the local business review functionality, or would your rather a more general, more popular location-based social network have their hooks in maps, like Facebook or Foursquare?
