I started a new thread because the VZW XV6800 does NOT use ICS as the other phones do.

I just got my 6800 to tether using the built in Modem Link app over USB with my Vista laptop without paying the $15/mo charge. Here's what I did:

1. Make the following registry changes:

HKLM\Software\OEM\WMODEM

add DWORD "CheckProfile"=0
set DWORD "Multi-NAI"=0
set DWORD "WModemDUN"=0

2. Start Modem Link (Open then select "Start" from the menu) with data disconnected and USB unplugged.

3. Connect USB. Windows will automatically download and install the appropriate drivers (you may have to click through some UAC prompts first to confirm).

4. Set up a new dialup connection using HTC USB Modem. Number is #777, user name is your phone number, and password is "vzw" without the quotes.

Now we just have to figure out how to get tethering over bluetooth to work. Any ideas?

EDIT:

If you wish to use Bluetooth tethering instead of USB, install the BT DUN CAB posted later in the thread and re-pair. Then perform the regedits listed above and set up a bluetooth dialup connection. You do NOT need Modem Link.
