Hello all! Im new to the forum and have only just got my G1. I have an 8Gb memory card and have filled it with music and vids. I have found that if you create three folders in your music folder, they will display in the corresponding menus.
ringtones
alarms
notifications
Now you can make your alarm or message ringer whatever you put in the folder on your memory card.
Just discovered this sorry if it is redundant info.
