after winpwn and quickpwn everything works on iphone except the ipod - music syncs but when I go to ipod on phone it says no content. Help anyone?

download bossprefs from cydia,
go into boss prefs and then click on more, there there is a button to fix some permissions, hit that, that should fix ipod

EDIT
i see ur not having problems launching the app

using ssh delete /private/var/mobile/Media/iTunes_Control, then re-sync
