Which Bluetooth USB adapter is best for 8130 ????
any recommend ????

Bluetooth USB adapter? Not sure what you mean.
What are you trying to do?

Shanker: You know the 8130 has BT built in, right? It doesn't need a BT USB adapter.

I am using 8130 as modem, and using internet with my IBM T43 notebook. Connected with USB cable. I want to replace with Bluetooth USB adapter instead of USB cable .
Any recommend ???

something like : D-Link Wireless Bluetooth USB Adapter - DBT-122
