OK, noob question.

DW has a Verizon HTC Incredible 2 with unlimited data plan. I understand that VZW blocks the WiFi capability of FoxFi, but the ten thousand articles online that tell me that say that I can use the Bluetooth DUN mode instead. We have assiduously followed the instructions to install the app and pair the two devices, but when we try actually connect from the PC, we get the error "The connection attempt has failed." We can tell it's communicating because a couple of seconds after initiating the connection from the PC, the phone bleeps and and asks if we want to allow the connection. We click to allow the connection, the gears turn for 15 more seconds or so, then get the "connection attempt has failed" message.

Any ideas where to look? Is there anything we need to install on the PC?
