TechCrunch went through the fine print and noticed that, with iOS 3.2 (iPhone 3.2 for iPad) Apple switched from using Skyhook and Google's location database to using their own, home spun, solution.
When reached for comment, Skyhook wouldn’t specifically talk about their relationship with Apple, but they did say that “everyone who has a platform wants to own as much of the location stack as possible. Location data is going the be huge and owning it is going to be the next big war in mobile.“
Indeed. Now roll Apple-acquired PlaceBase and Poly9 Map layer brain-trusts into the equation, and what will we get?
