what app can I use to sync my ipod nano?
I use Open Suse 11.2 and it is 32 bit 
I am using gtkpod. I have a 5g nano and had a bit of trouble geting it working. It worked fine with an older iPod.
Here is the link to the thred that I started to get things working. I don’t know if it is 100% yet, as something caused the iPod to show that there was no files on it. I had to get back into iTunes to reset it. That only happened one though.

I have a 5g nano too but i guess I’ll use a windows pc to sync for a little while
