LG VX-8100

I got my 8100 when it first came out and I was pretty ticked off about the phone not being able to play mp3's and now as I read through all of these threads and it sounds like everyone has figured out how to play mp3's. I was just wondering how to do this. Does it have something to do with the new software that has been released for the phone, which I do not have because its not here yet where I live. Could someone please give me some good info on how to get these mp3's on my phone. Also what does that new update do for my phone. I have a mini SD card and I have figured out how to play video's and I am liking it. So please someone help on the mp3's Thank You.
