The same I guess will be the case with this. Apple has decided to ban in-app location-based advertising for its most popular platform, the iPhone/iPod Touch. Given how much of the market the iPhone currently holds, and how much it is set to affect the the market in the future, I'm sure this is a move we will remember. Here's more from the article:

The company announced that it is blocking applications that use location-based information primarily to enable mobile advertisers to deliver targeted ads based on a user's location. Industry analysts are speculating whether that decision could have something to do with its pending acquisition of mobile ad network Quattro Wireless.

“Apple is acting like they normally do—they want to control the experience and the use of their devices and applications,” said Neil Strother, Kirkland, WA-based practice director at ABI Research. “This a way for them to make sure the end user isn’t getting spam and controlling what goes into iPhone applications.

Here is the 'advice' given to iPhone developers, on the Developer Connection section of its website, regarding location-based advertising in iPhone apps:

The Core Location framework allows you to build applications which know where your users are and can deliver information based on their location, such as local weather, nearby restaurants, ATMs, and other location-based information.

If you build your application with features based on a user's location, make sure these features provide beneficial information.

If your app uses location-based information primarily to enable mobile advertisers to deliver targeted ads based on a user's location, your app will be returned to you by the App Store Review Team for modification before it can be posted to the App Store.

You can learn more about using Core Location by reading the CLLocationManager Class Reference and downloading the LocateMe sample code available in the iPhone OS Reference Library.

I'm looking forward to seeing how this turns out, but I'm sure the Quattro acquisition by Apple has everything to do with this move -- it's pretty evident Apple wants full control over the advertising that goes on in its platform. That's where the big bucks are, and the fact that both Google (who recently bought AdMob) and Apple are so actively looking to take a big piece of the mobile marketing market shows just how true that is.
