I'm thinking Apple should allow the native phone app to make calls over WiFi instead of over the cellular network. They should also allow the messages app to send SMS's and MMS's over WiFi. I'm not talking about iPhone-to-iPhone communication. I'm talking about allowing people to call and text whoever they want without using the network. That way, calls don't count against their minutes and texts don't count against the number of texts their carrier allows them to send. I would be infuriated if the carriers reacted negatively. In fact, I'd hate those carriers. I'd try to stay away from them.
