If you use your Research In Motion (RIM) BlackBerry's Bluetooth wireless connectivity, it's probably to connect to a hands-free headset or ear piece so you can drive or take notes during conversations, or a set of earphones to beam your latest tunes from your device sans wires.

But did you know you can transfer files like photos, voice notes and songs from your BlackBerry to other compatible mobile devices using Bluetooth? The Bluetooth file-transfer technique can come in handy in areas with poor or no service or when you need to get files off an old device which no longer has active service.

You can transfer files between a wide variety of compatible mobile devices, but these instructions cover only BlackBerry-to-BlackBerry Bluetooth transfer. Generally, you need to be within a range of roughly 30 feet of another Bluetooth-enabled device to connect. We used a BlackBerry Curve 8320 and a Pearl 8130, but this process will work for any 8800 series device, as well as a number of additional RIM smartphones.

1. Enable Bluetooth connectivity for both devices

From the BlackBerry icon screen, click Manage Connections and check the box next to Bluetooth.

2. Make the BlackBerry devices discoverable

Click Options on the devices' icon screens, and then select Bluetooth. From there, hit your BlackBerry Menu key (the one with the seven-dot RIM logo) and again click Options. Then set the Discoverable option to Yes and exit the menu by hitting Escape (the key directly to the right of the trackball on 8800 series devices). Don't forget to click Yes when a dialog box asks you if you want to save the changes.

3. Pair the BlackBerry smartphones

Go to the BlackBerry icon screen and once again select Manage Connections. Then scroll all the way down to the Bluetooth Options menu item and click it.

Hit your BlackBerry Menu key again and select Add Device. The BlackBerry will then search for Bluetooth devices in range. After it has found one, it will show the name of the device and ask you to confirm that it's the correct one by clicking on the device's name.

After you've followed this process for both handhelds, you'll be prompted for a numeric passkey to access the devices. The default passkey is 0000, so unless you've changed either default code you'll need only to enter four zeros.

After the connection is finished you'll see a dialog box on both devices that says Pairing Complete, and the device you wish to connect to will appear in your list of Paired Devices. This list displays when you first click Bluetooth Options inside the Manage Connections icon.
