Ok, here's what i found worked on my phone to get a custom notification for voicemail, and still have the text notifications, email, etc., all use your selected sounds. I used free mp3 wma ogg converter to convert my mp3's to ogg files, put them back onto my sd crd, then used root explorer to put them into system/media/audio/notifications. Once I selected the custom ogg file as my standard notification, all my other notifications work exactly as they should. Now, here's my issue...I'm running velocity 1.1, and my phone has no issue with this procedure. My wife's is stock, 2.2.1, rooted, and this won't work on her phone. It flashes really quickly that it's copying, but doesnt show up, even after reboot. If i use move, the file disappears from where it was, but still doesn't show up in the /system/media/audio/notifications. Any ideas?
