Try getting a micro memory card with adapter. If you have windows media player on your computer, it is real easy. Just put a cd in or use music you already have on there to start. If it is a cd you put in, you will first have to choose "rip" music. Next click "sync" and put your memory card with adapter in your computer. Windows media player will recognize it. Just drag the music to the right under where your card shows. Click "Start Sync".
The other way would be to buy a Data cable and go thru the same process. Be sure to plug the cable into the computer first, then the phone. The best and cheapest place to buy a data cable is Amazon.com. I bought one for $3.23. I hope this helps. It works great for me.
