Yes, we have some GTA02 boards w/o display...

Could it be possible that those "greedy bastards" don't even exist except
in your wishful thinking?

This sounds like shooting yourself in the foot. As soon as I would do that,
I can't sell you a GT04 any more because I don't receive any more of these
modules. So it is not a realistic option.

And you would be astonished how tiny information we really have. Almost
everything we know has been transcribed into valuable information and
is included in the user's manual. This are AT commands and the pin layout.

By going to the official product page you can also find out that there
is a QC MDM6600 inside (same as iPhone 4). But that does not mean
that we have received any information about that chip or its firmware...
We are at least on the output of the third level information filter from QC to us.

It is in this respect like buying a UMTS-USB stick in a blister pack where
you don't get a service manual included.

Finally you will find by research that there are some projects to write
alternate firmware for MDM6600 devices. But that is all, that I know that
those projects exist (I think one was mentioned recently on the GTA04
list [1]).
