I found this great free program for getting your iTunes playlists on non Apple devices like cell phones that can play MP3 files. I have a sony erricson K850i cell phone with a 4GB memory card, and wanted to get my music from my iTunes Library on it. I searched around and found iTunes Agent. This program will allow you to import your music, or podcasts from your iTunes library into your MP3 player or other devices that can play mp3 files. You can find the file at the iTunes Agent site
http://ita.sourceforge.net/, and the instructions on how to use it. Please make sure you read the documentation on the usage. It's very simple to get it setup, but does require a few steps before it will start working with your device. If you have problems, let me know and I can give you a hand getting it working.
