I have an LG Optimus Zip phone with Verizon/SmartTalk and I've been trying to figure out how to add custom notification sounds (for texts, email notifications, etc) to the phone. I tried creating a folder called Media on the sd card and then a new subfolder named Audio. Under the Audio folder, I created two more new folders named Notifications and Ringtones. I downloaded a trial mp3 (NewTextMsg.mp3) to the Notification folder but when I go to Settings>Sound and chose the Notification Ringtone option, I don't see the new custom ringtone listed among all the stock ones. Has anyone been able to do this without installing another app to do it?
