Got my new Casio GzOne Commander. I've downloaded songs that I want to be a particular person's ringtone. Set it thru Android and it says it is there. Used person's phone and called my phone. The original default tone played. Hung up and redialed. The personal ringtone I set played. Waited an hour and did it again. First, default....then again, personal tone. What is causing this? Gremlins?
