I want to transfer music from my iTunes library onto my phone. After connecting my Droid X to my computer, I open the media share on my phone. I get a message saying "Memory Card, The memory card is missing. Insert a memory card to access media share". I called the Verizon store where I purchased the phone, and they told me that I need to convert the music to mp3. I did that. But I keep getting this message on my phone anyway. What does this message mean? I am not a tech savvy person. What do I need to do to transfer my music to my phone? In simple terms. Thanks.
