I created a folder on the micro SD card called "Music".  I put 300 songs in (more to follow).  One of them is Scotland the Brave which I use as a ringtone.  Once the phone is working I went to Music and found the song.  Then bring up the menu and one of the options is Ringtone.

Doing it this way allows you change it if you feel like it.  I think you can set different ringtones for your friends but I haven't tried it.

I only change my ringtone once a year.  I switch to an Irish medly in the month of March.

P.S.  I'm Jewish.
