I have been using Ringo with my 650 and T-mobile service for some time now and it has worked great. This week, T-mobile upgraded there voicemail system to use a traditional voicemail icon/alert versus the old SMS alert. Now, the only alert that plays when voicemails come in is the default Treo alarms. Does anyone know how I can get my mp3 alerts to play using Ringo with this new voicemail system?
