The Galaxy S3 AT&T should now be different and in order to check if the root was successfully performed just search for the BusyBox app. It should be displayed in the app drawer.

To be more specific, what you can now get exactly are WiFi tethering in terms of connectivity,then also a CWM Manager and a ROM one.
