Does anyone know exactly how to put your own music onto the sanyo 8400 in particular?  I had a guy in the shop I work in who reckoned he had put heaps of his own music into his phone and couldn't find any of it ever again.  His Micro SD card definitely said it was empty!  The shortcuts you get with the phone tell you how to download music from the telecom music store (at $1.99 each!) but not your own files.  the phone has mass storage, comes with it's own USB cable and micro SD card of small memory, and I managed to get photos from the camera onto the card today, but the music thing bamboozles me.  My sanyo M1 is very easy, but it doesn't have a card, no need, it's got 1G of memory...  I get the feeling one needs to create a folder or something, but I am a bit hazy on it...I haven't even worked out the media player/chanel listing/media listing thingy yet.  I need to know how to set up the whole show and I need to be able to explain it to non-geeks!  Help!
