No Bluetooth PAN tethering?

[rallynavvie]

All of the tethering threads I've been reading for the past couple weeks here have to do with USB tethering. What of Bluetooth tethering on the TP2? I just upgraded from a Mogul to a TP2 a week ago and assumed that the same WM hacks for tethering would work but just to be sure I followed the tethering steps listed here with my TP2 but it won't connect with my laptop. Before/after comparison:

Before:
With the Mogul I would use the ICS app, select Bluetooth as the connection type, then hit connect. It would always prompt me to make BT visible but I hit "No" because the devices had already been paired successfully. Then on the MBP I would find the Mogul in the BT device list and select "Connect to Network" (or something like that) and the two would connect and I'd have internet on the MBP. Unfortunately I can't recall which hacks were used for the Mogul as it was nearly 2 years ago I set up BT tethering for my Mogul (and it had worked the entire time).

After:
On the TP2 I installed just the hacked ICS CAB and selected BT as the connection type and it went to the BT settings controls where it then said my MBP did not have Bluetooth PAN capabilities even though my Mogul used the BT PAN just fine on the MBP. I also noticed that when synching the devices the "Connect to Network" doesn't appear in the BT device menu like it did for my Mogul. So I went and did the registry tweaks also listed here but the Bluetooth option doesn't even appear in the connection type dropdown anymore!

I'm guessing the two devices have different BT stacks or something and the new one isn't allowing the MBP to synch to its network? I was about to give up and just use the HTC wifi router but that CAB won't install, it says I don't have access rights to install (doesn't the RAPI hack override that?). I'd much rather just use the BT tethering instead of wifi because BT has used less battery than wifi in the past.
