So sorry if this has been asked a hundred times or is in the wrong place but I have tried looking and am just plain lost. As you can tell I am very new to all of this so the answer to my question may seem obvious to you but to me..... HELP! If I buy the itouchDS, is the firmware stored on the cart or the micro SDHC? Do I have to buy the micro SDHC with the cart to get it compatible or can I buy the micro SDHC seperate from a different store? I don't like the price or know the brand of the micro SDHC being sold where I want to buy the itouch. Also can someone point me to directions for updating the firmware or whatever I have to do once I recieve these. Thanks from a total noob. All help appreciated.
