   The issues are as follows:
   1. A delay due to the timing of chinese new year. factories shut down.
   2. We needed to check that the ALSA states in the production image
     gave a good experience on the A7.
   3. Engineering a smooth transition in the channel between the A6
      which is in inventory, and the A7.
   4. Coming up with a plan for fixing as much of the buzz issue on
      existing stock as possible.
   5. Working with our distributors to roll the A7 out.

   Sorry, but I got the hammer on this one. I didnt want to launch A7 
and  require customers to reflash as their first chore. Further, I 
wanted to go over the test results myself for the phones sent to test 
before I committed to SMT and assembly. I did that in late feb.

  Yes, that was a concern of mine as well, so this too had to be checked 
and verified. The complication being that a reworked A6 can only be 
distinguished AFAIK by visual inspection and not by checking a bit in 
the hardware. Joerg may correct me on this, but I believe the only ALSA 
state setting that may be effected is the mic sensitivity or gain ( 
can't recall, exactly )

  When distributors start to take shipments of A7 ( see 1-5 above) we 
will make an announcement. The buzz fixing program is coming together
with Tuxbrain taking a pivotal role in working through the logistics
with me.
