I came from a Choc 3 flip and i really liked how i could choose a sound for a missed call and when someone leaves you a voicemail from that missed call. Scenario: Mother in law calls. I ignore the call. 10 sec later my phone plays the "tone" i chose telling me i missed it. 1 min later my phone plays another "tone" alerting me that she left a voicemail. Can this be done on my eris? Or do I have to settle for one single notification sound for EVERYTHING?
