Hi, I thought I had changed my default ringtone to an mp3 but when I tested from a phone not programmed the ringer had not changed. I went to music>found my mp3, hit settings and selected ringtone. Also, how do you simply stop music in these things? I have only found the pause button but no way to stop the music altogether. EDIT: Ok for some reason it took setting the default ringtone twice before it worked. Can anyone help with the second question? How to stop music instead of just pausing it?
