The ones that were originally preloaded with the droid? I used to be able to set ringtones as alarms. All i had to do was set default ringtone to "Jay-Z" then create an alarm and my ringtone would automatically be my alarm tone. After force updating to 2.0.1 and formatting my SD card I cannot do this anymore. I have tried creating the "alarms" folder but that requires me to manually place ringtones in there.
