iOS6 facebook integration

Updated my 4S a few days ago to iOS6, loving it so far. But I do have one question regarding facebook integration. When I tried to log in to the app through the settings app it says it will sync all my facebook friends into my phonebook and I do not want to do that. Is there any way to avoid that?

I did log in to the app by just opening it from the springboard and it doesn't offer the integration and the app works just as well as on iOS 5.1.1.

What are the benefits of having my account integrating into the phone instead of just logging in to the app the "classic way"?

Thanks.

 

Oh silly me. I thought it would sync everything and I would have to delete every contact manually.

Thanks!
