Did Apple just ban location based ads? Foursquare/Gowalla in trouble?

Coming up soon: all ad-supported iPhone apps will include some sort of "weather at your location" feature.

I also wonder if this is a way to strike at Google via AdMob...

why will foursquare and gowalla in trouble. Apple's blog clearly says you cant get user location only for ads but if you are using it for other features you can get it and use it anyway you like.

I don't think this is a huge deal. There's a difference between writing a location based app that happens to pass along your location information to your ad network when it requests an ad, and writing an app that has nothing to do with location, but pulling location data out of the GPS solely so you can get better targeted advertising rates. The latter may be considered wasteful use of the GPS.

I don't think this has any implications for Foursquare, Gowalla, or any of the other half dozen location based apps out there.

The ads worked just fine today. From my understanding of the article, neither company is in trouble.
