so im new to iPods and podcasts of the sort, and whilst its been a week since ive ordered my iPod and it still hasnt even shipped yet, it will still be a while before i use it. but anyways, i was just browsing around and came upon the podcast situation. how do these work? do you have to sync your ipod to your itunes everyday to get them, or is there some other magic involved? also, are said podcasts free? i always hate putting in my acct info with apple cuz i can never tell if they are charging me or not. thx in advance.
