Xperia X8 :: Most Of Alarm Tones Gone With Upgrade?

I'm writing about my X8 that I've upgraded from Android 1.6 (Donut) to Android 2.1 (Eclair) between yesterday and today. I regret that with the upgrade a lot of "alarm tones" are gone, including one in particular which is so cool, I can't remember the name but that begins with "multi" - it's a combination of more tones (drin, chicken, bell, etc.).

I did a regular backup rand restore but I don't think those wake-up tones are normally backed up or considered in the backup process. I'm asking you what I can do to have back what I had but seems to have been lost with the upgrade. Now the mobile phone's alarm ringtones available are very few and I think a upgrades should add, not remove.
