I think that this may be happening:

I supose they're still reprogramming the devices (with the latest fw)...
So they only send the codes when the a batch of units (50?) become ready to ship...
The first 50 (or so) units got done, and they've sent the codes and started shiping those... everyone else on the list will have to wait a little longer...
(maybe they-re reprograming the units, manually, one-by-one...)
but it's already been 4 days...

can anyone confirm this?
also, can anyone with an "inside" contact let us know what's really happening?

thanks!
