I have a sound from metal gear solid game, specifically the sound when the guy gets a call, and when he is detected by an enemy guard (both, in my opinion, perfect for message alerts and ringtone)

The problem I have is that I only have the phone, an SD card, and a USB SD adapter, and I can't seem to get anything on the card to be set as ringtone, or transfer stuff from the card to the device.

Any ideas?
