Is there a way to add MS BT stack to stock TP2?
 

If not is there are ROM with it included along with WM 7.0?

So far there haven't been any ROM's (that I know of) with the MS BT stack. HOWEVER, many of the 3rd party ROM's now have an UPDATED BT stack that has fixed many of the issues with the original BT stack (unable to hang up from BT device, slow BT connections and answering, difficulty with MS Voice Command). The updated BT stack was released in the 6.5 USCC and Verizon roms and has been used in most of the newer 3rd party roms too.

Windows Mobile is not yet released, so nobody has it.

And as for the MS bluetooth stack, there's a bounty out there for anyone willing to replace the widcomm stack with the MS one. Easier said than done. Much, much easier...

To more directly answer your question though, no, I can pretty much guarantee you will not be able to add it to the stock ROM. If -- and it's a big if -- anyone were to figure out a way to put the MS BT stack on the TP2, it'd be through a custom ROM. I don't even know if that will happen.

And regarding your second comment about WM7, it's nearly certain there will be no official upgrade to it for the TP2, and it's questionable if you'll even see unofficial versions.
