I decided that it's finally time to update to the current 2.1 firmware. On my ipod touch right now, I am using firmware 2.0. So all I do to update is to connect to Itunes 8, and hit update to 2.1??? Then if I want to jailbreak, use quickpwn 2.1 to perform the jailbreak?? I have the aptbackup from cydia to backup all of my cydia apps.... but everything else will be wiped out right??
