I'm at work, no access to my USB cable or computer at home to save to SD card. I emailed an MP3 file from my work computer to myself. I can play it fine on my DriodX, but am not able to save it to the phone. I have ringdroid installed and will use that to translate it into a ringtone. Any tips on how to save it to the device or should I just wait until I'm home to copy it over?
