1) Download the windows drivers for the Samsung Sway as mentioned here. http://mark.cdmaforums.com/SAM-DRVR.htm I downloaded the Samsung USB Driver (MCCI 4.34) WHQL v3.0.zip drivers from this link http://mark.cdmaforums.com/Files/Samsung%20USB%20Driver%20(MCCI%204.34)%20WHQL%20v3.0.zip
Extract the file using winrar.
Connect the phone to the computer and the phone should pop up a message asking to synch data (or music) to my phone or my memory card.
Select memory card. This then opened up a windows explorer window on my PC and I simply dragged and dropped mp3s from my PC onto the phone.
