It was easy. First, sound like you know what you are doing. I told the nice woman immediately that I needed an esn change. She asked me what the esn was, I told her, and she said, "Ok, this is an Audiovox 6700?" I said, "Yep." She added it into the system, and viola!
That was the easy part. I just didn't tell her it was a ppc6700.
