I am using ubuntu 13.04 and my ipod has has ios6, and its 4g. I have already tried libimobiledevice and also tried it with gtkp which says "Error initialising iPod: Unsupported checksum type". I really want this feature as I do not want to depend on windows for my music transfer to ipod. I don mind if I have to manually organize my music (instead of syncing i mean) but i really want to make it work help please!
