Just set my wife up with the new yahoo mail app that came out last week. Very nice that it pushes now. I can't, however, get it to make any notification sounds. She has Zedge for downloading ringtones and notification sounds and her general notification sound is set as a sound from Zedge at this time. Will yahoo only use stock sounds so it doesn't play anything? I do have the box checked to use notification sounds and vibrate in the setting.
