I finally got the D-Link DBT-120 dongle to work with my 7130e. Here's what I did:
1. Installed the latest Kensington 33348 dongle software/drivers for WIDCOMM (downloadable from kensington.com site under support).
2. In Control Panel, did an Add/Remove of the WIDCOMM software (remove) and rebooted PC.
3. Plugged in D-Link dongle and confgiured it using installed software (listed in device manager as Generic Bluetooth Radio).
4. Followed instructions from RIM knowledgebase

Works like a charm even though RIM states in the article D-Link is not supported.
