Does anyone know how to add personalized ringtones to the calender ringtone selection. I have been trying to do this with a Droid 2 Global, and have been unsuccessful. Have the following apps downloaded (Change Ringtone, MP3 Ringtone Maker) they work great for personalizing ringtones for the phone ring, notifications for text, email, etc. However, I cannot seem to get any of these file to show up in the calendar ringtone selection. Please help!!!!!
