The one in the commercial is the generic 'cellphone' ringtone. It was just put in there to help people identify the iPhone as a phone. I dont think they actually wanted people to use it.
I actually liked it and am interested in using it. Seeing as it sounds like it would stand out, and so many people are using "Old Phone" and like normal phone sounds, I think it would be popular.
