To transfer files from your computer to your phone, YOU NEED:

USB connection cable and a Memory Stick Micro M2.

Insert the card, turn on your phone, and plug the cable in accordingly. On you phone, three options should pop up;

choose "File Transfer." On your computer, go to "My Computer." In a few moments, "Removable Drive (?:)" should come up. Double click on that.

You shouldn't have to install ANY software. Ignore any attempts by your computer to install software. There should be folders already made. Go to the one labeled "Music" then "Ringtones." Just drag the songs you want in there.

After you're done, return to "My Computer," right click the "Removable Drive (?:)" and press eject. Wait until your phone says it's okay to disconnect the cable. After your disconnect your cable, wait a moment for the phone to restart and turn on again. Go to "My Stuff" and go to your Ringtones folder. Press "More," select "Use As," and select "ringtone." There you have it.

If that fails to work, try installing SEUS USB Flash Drivers and go through the same procedures again.
