There are two ways to do this – either through the supplied Roxio Media Manager, or by simply dragging the file to your device if you have mass storage mode enabled.  For Media Manager, we can start with the same steps as when downloading a ringtone from the mobile device, however this time instead of “Email Ringtone”, select “Download Now!”.  Save the MP3 file to your desktop (or any folder you choose).  Open The Desktop Manager and load the Media Manager.

When media manager options, select the “Folders” tab to view the files on your PC.

Scroll to the folder containing the downloaded ringtone (in the case “Desktop”) and select it.  Now in the bottom left pane, scroll to your ringtones folders on the device (or on the memory card, depending on your choice) and select it.

Now simply click “Copy Down” and you will be prompted on how you want to convert the file.

Select “Convert for Optimal Playback” and click ok.  The file will transfer to your device.  Your ringtone is now installed and you’re ready to go.

Perhaps the easiest way to get ringtones onto your device is to have a memory card installed and enable Mass Storage Mode.  To do this, install a memory card into your device.  Go to Options > Media Card.  Here you need to enable Mass Storage Mode by changing the option to “On” & also change “Auto Enable Mass Storage Mode When Connected” to Yes.

Now when you connect you device to your PC a dialog will pop up and ask you what you’d like to do.  Select “Open A Folder to View Files” and you’re memory card will display all the folders on it.

Navigate to the BlackBerry folder:

Navigate to the ringtones folder:

Now simply drag the ringtone you downloaded from your PC into the ringtones folder.

And that’s it!  The ringtone is ready to go!

Now, if you choose to remove any ringtones, you can do so by navigating to your ringtones folder on your PC.  Simply delete the files from the folder and they will be gone.  You will need to do a battery pull in order to remove them from your list of ringtones however.

Take the steps above to set the tone for your alert for each profile.  Unfortunately there is no easy way to edit all your profiles at once, so if you plan on using more than one (Loud for home, Quiet for work etc.) you will have to edit them each one by one to change the tones, volume, vibration etc.

This method also works for any MP3 files you have on your PC.  You can download them from other sites, or maybe just rip them from your own CD collection (its hard to find a good Tesla tune online these days).

That’s basically all there is to getting custom ringtones on your device – either by downloading them directly to the device, or loading them from a PC via Media Manager or Mass Storage Mode.  These steps apply to choosing and setting a tone for phone, emails, sms, mms, alarms, calendars etc.
