I haven't heard anythink back as of yet. Not sure if they even checked there junk mail.
Also, we know that other Mfr's maybe using QCs Streamboost technology, If we think about it, who's to say that these issues with SB are not being seen on those products as well? We can only presume that QC is using the same SB code and engine since SB core belongs to QC. Just a thought I had.

I still have the email of the person i was in contact with at Qualcomm.
Although I have not spoke with him in a couple of months.
I would try tweeting @QualcommAtheros and ask for support help for streamboost.
That's how I got in contact with support the first time.
If ya need I could PM you the email of the person I was in contact with but I would try a fresh start first.
