If I get a Motorola EM326g, or something similar, how do I put MP3's on it? I have a really old computer, so the only thing on it I may be able to use is a slow usb port. The phone description says in order to use the MP3 player, I need a cable and an SD card. But, with how old and slow my computer is, will I be able to do anything on it, and how? Would the Patriot Memory 8GB LX Series SD Card, High-Capacity work? Also, how do I know what cord to get? Thanks!
