You can select the output directory for the DRM packager to write to when creating a DRMed file from your MP3. Once that file is created then you need to connect your phone using the USB cable and select phone mode when prompted on the phone. Once connected, you click on the the phone icon on the task tray to select "File manager". When File manager comes up, you should see an folder that look like the phone, double click to go into it and you should see 2 normal looking folders. At this point drag your DRMed file into the window that contain the 2 normal looking folders, but makesure not into either of the 2 folder, just the open space within that window. Once the transfer is completed the phone will promot you what you like to use the MP3 for, then you can select to use as ringtone.
