found the above post in xda. Sounds like the 6.5 upgrade that was spoken of in the thread was not a home run. If you look deeper in that forum...you'll find lots more folks feeling the same way.
I don't think we can count cooked WM6.5 ROM's because we are all anxiously waiting for the official upgrade. PLUS most cooked ROM's are pretty much optimized anyway.
Thoughts??
