I went back to check the settings on my 321 because I'm having trouble with it reestablishing the itunes connection after waking from sleep. Sometimes I have to manually change it back to the 321 in the itunes preferences.
I accessed the 321 to check the itunes server settings and I can not make any changes it is simply blank. the only choices are save or don't save settings. I remember initially being able to set it to the itunes folder but I no longer have a choice. I've checked on both a mac and PC
here are some screen shots: FW 1.02
OSx

Windas

If I select either choice it will not reconnect with the 321 and says it can't find server. I have to wait awhile before I can reaccess the 321
