Just bought a Nano 2gb for my wife for Mother's day. We were going through the menus and checking things out and found that it says formatted for Windows. She'll be connecting it to her iBook. Do we need to do anything regarding formatting? Also, I think that there is a newer os for the Nano. How do we update? Sorry these questions are probably really "stooooopid" but it's our first iPod. Thanks in advance
