I am using OS X Leopard, iTunes 8 and an iPod nano 16GB (current gen).
I have the bug somewhat described here:
http://support.apple.com/kb/TS1410?viewlocale=en_US
My iPod won't show up in iTunes.
It DOES however show up in the Finder (desktop).
Apple's site says:
1. Reset your iPod.
I tried that already.
2. Retry with a different USB or FireWire port.
I tried that already.
3. Restart your computer and make sure you have the latest software updates installed.
I did that already.
4. Remove iTunes software and then reinstall iTunes software from latest versions on the web.
I already deleted iTunes (including iTunes Helper after restart), restarted, redownloaded and reinstalled iTunes.
5. Restore your iPod. See Updating and Restoring iPod Software in the user's guide.
This step requires iTunes to detect an iPod. (see here) Since iTunes CANNOT detect my iPod, it WON'T let me restore it.
--> I AM STUCK.
I tried using the disk utility to erase the iPod's partition, but I got the warning:
(Yes: "OWNER'S IPO" is the FAT32 name of my iPod, which is FAT32 formatted from my windows PC, and is recognized on my Windows PC iTunes, but I do not have access to that PC here)
I am afraid to use Disk Utility to erase my iPod's partition, not because it would erase all my music (I have it backed up), but because what IF iTunes STILL doesn't recognize my iPod after I erase entirely all its disk???
Then I am stuck with a $300 tiny brick. 
Help me please.
Thank you.
And I did search for answers to my problem. Since iPod non-detection is common in iTunes 7 but I am using iTunes 8, and unlike everywhere I see, a restart or reinstall of iTunes didn't fix the issue.

I tried using the disk utility to erase the iPod's partition, but I got the warning:
Erasing a volume will destroy all information on the volume. It will not erase information on other volumes on the same disk.
WARNING: This volume is on an iPod. Erasing the iPod volume will disable some of the iPod functionality.
Are you sure you wish to erase the volume OWNER'S IPO
