I did try the script (by Fanoush) and tried changing the profile to NAP from GN.
Still no go on my N810.

Is there something that different in a N800 with OS2008 and a N810 with OS2008 that while it seems to work for N800 users it doesn't work for N810 ?

When I run the script on the N810 with Internaet sharing on on the Blackjack, the bluetooth icon turns blue for a sec and then white agains and disconnect on the N810.
