A report this morning says that Apple will integrate Yelp check-in's in the new iOS 6 Maps. Now I love Yelp, but I don't use it to check-in. In fact, I didn't even realize it had that feature. I like to be more selective of how and when I check-in. Do you check-in using an app? Is it Foursquare? Is it Facebook? Do you use your location when tweeting? Thoughts on Yelp in iOS 6 Maps?
