AT&T Lumia 920 - 2 Freezes in a few days maybe rel...

Question

Hello,
I've been using my AT&T Lumia 920 for 8 days. Within the first week I have had 2 freezes. Both were while using Bluetooth, but that may be coincidental.
I am not happy about these glitches as I was previously using an AT&T Lumia 900 since April, and it never had problems like this. I expect the 920 to be an upgrade in every regard.
I am seeking:
An explanation as to the cause of these issues.
A permanent solution that will prevent these issues from recurring
The specifics of the 2 incidences are:
First incident:
I was driving & talking on my phone with my Plantronics Voyager Bluetooth headset. I parked at BestBuy & went inside continuing my phone call. In less than 60 seconds, I realized that it seemed like the person on the other end of the phone was being too quite. So I thought maybe the call dropped. I pulled the phone out of my belt holster & found that it showed that the call was still connected. But I could hear nothing. The screen was essentially non-responsive. Within about 1 minute, my screen went black & I couldn't get the phone to do anything. I kept trying to to a soft reset like I did with my Lumia 900 a few times (power button + volume up). This didn't work (I have later learned that the Lumia 920 uses a different button combinatino (power button + volume down). I gave up using my phone & asked the Geek Squad boys if I could use their phone to call my customer back to finish the discussion so that I could confirm I was purchasing the correct product for him. About 30-60 minutes later, I was still periodically trying to figure out how to get my phone to come back to life. I pressed & held two buttons (presumably power + volume down). The phone vibrated & rebooted. Thank goodness.
Second incident:
I was traveling & dictating an email (which I'm glad that Windows Phone 8 now lets us dictate outside of TXT messages. :-). My first attempt returned no results. I then pressed the microphone button again & retry dictating. At this point, it did something unexpected (I really don't recall the exact specifics). From that point, further attempts to dictate did absolutely nothing. I then decided that I'd just type the email instead. I picked up the phone & pressed in the body of the email. The onscreen keyboard appeared. But none of the keys actually typed or did anything. At this point (of course a bit irritated), I tried to get out of the email, and realized that the phone would not really let me do anything. It displayed the empty email and gave me a flashing cursor, but no buttons or keys would do anything. It was like they were all being ignored by the phone. Then I had this though.... After my previous lock-up, I had read a little bit online that some Lumia 920 users had experienced lock ups when using bluetooth. So I thought, maybe if I power off my bluetooth headset, the phone will break the bluetooth connection & maybe will release control of the phone back to me. So I powered off my bluetooth headset. Sure enough, the phone immediately returned to normal (although it did first quickly make a couple of sounds & display regarding the dictation [like basically the last time I pressed the microphone button, dictation wasn't able to come up, so now it finally did come up & then went away again all within about 1 second]). After powering off the bluetooth headset, my phone has been fine. No need to reboot. A few days have passed with no more issues.
So in summary:
Is there a problem with the phone's bluetooth support?
Is there a problem with my headset (I don't think so, it works on other phones just fine, and it works on this phone 98% of the time without problems)?
Who is going to fix the bluetooth problems & when (Nokia or Microsoft)?
Can they be fixed, or are they problems inherent with the phone's bluetooth chip which are irreparable?
Is there any sense in me going back to the AT&T store & swapping for another Lumia 920? (I don't think so. Seems like most everything else with the phone works well [I've had a few other isolated incidents with other things, but so far I've written them off as software glitches that Microsoft or Nokia will fix with time]).
Who should I be reporting this issue to (AT&T? Nokia? Microsoft?)? What is the correct support channel to get the issue resolved most quickly? (I am very willing to work with a competent tech support person to troubleshoot & track the issue over time if necessary in order to help facilitate identifying the root cause of the issue so that a proper permanent fix can be implemented by Nokia or Microsoft.
Have any other users experienced this same problem?
Thanks for your time in reviewing my issue. I have been very excited & enthusiastic about the Lumia 920 & Windows Phone 8. I have tried to promote it with my friends and family. However, when I hit an issue like this which didn't exist on my Lumia 900, I find myself feeling a bit embarassed & frustrated.
By the way, to my knowledge I didn't have any other programs running on my phone during either of these incidents (definitely nothing else running in the foreground).
Sincerely,

Don't expect support here. Nokia does not bother to pay a tech or two to support the people who have bought the 920. Not really a point to these forums.
Anyways, i have huge bt issues as well. Cannot connect or see my jawbone. In truck with pioneer nav system (it is illegal here to use a phone without handsfree in vehicle) it links, but when i make a call or receive a call it shows the phone off the receiver icon so it knows call in progress, but i either get no sound from the caller... at all, or i get a robotic mess i cannot decipher. when i cannot hear anything, people can hear me, but when i hear robotic, people can hear me but with distortion. However, when it reads a text message, the phone voice is fine through the system. Because i have to turn bt off then to use phone, i have to return this handset and just go back to android.
Have also had this drop calls a few times now as reception is probably the worst i have seen in a decade... even drops in downtown core. Battery life poor because i assume its always struggling for a signal.
