Finally i have succeeded to mount and be able to read and write hfs+ iPod on my ubuntu 9.04.
If you have the same problem to mount Mac formatting iPod, you might not have to ask your friends for a Windows machine.
I can transfer music using bansheen and gtkpod.

sudo mount -rw -t hfsplus -o force,umask=0000 /dev/sdb3 /media/IPOD

Cheers.
