I purchased a samsung 930. A friend told me to purchase a SD card and a device to transfer music from my computer to the card. Although the music appears to transfer to the card I cannot get it to play on the phone. It doesn't even register on the phone but it does when the card is in the computer. I converted the files from MP3 to WMA...still didn't work. Verizon says I must purchase the cable they have to tranfer music from PC to phone card. Please help. I'm using windows media...vcast , etc. Nothing seems to work.
