There's the MVP for Apple Maps. Doesn't mean it's the must useful for everyone, but it's the feature-set that Apple set it's sights on with the new Maps app.
I do think it was stupid to punt on business listings and use Yelp, but I haven't heard of any better options.
Yelp is building relationships around the world with the key "business listings" companies in each country. For example in Australia they have a relationship with Yellow Pages. The problem is that Yelp isn't in every country but they will be now that they are flush with cash.
So Apple can leverage the work they are doing rather than duplicate efforts.
The app itself is great. It is smoother, faster and technically better than the previous Google Maps implementation. The problem is that the data is about 50% accurate.
It is exactly what an MVP is supposed to be.
