Apple's iOS 6 is being released Sept. 18 for iPhone and iPad owners, and major changes in the built-in Maps app might affect your business.

The new Maps have completely dumped Google's information. Instead, local listings are powered by Yelp.

I know many small businesses depend on Google listings instead of Yelp's, especially in rural areas like mine. If you own a business, be sure that it's listed in Yelp, or if it already is, that you've claimed it. Otherwise, you risk losing potential customers.
