+1 from me ;-)

That seems technically a smaller problem than a software issue, and seems to
imply that there is no hardware issue? Such a pity NDA's can have such an
Concluding I can only agree with Josch: there's a lot to play with, there
seems to be more there already in this EA board than there was in the GTA02. I
also agree that voice calls would be nice, so that I might actually replace my
day-to-day motherboard instead of the testing one.

Haha, it sounds like: thanks for enjoying the ride so far, and now to work!

No matter how: NDA is NDA. It's difficult to open up without permission from
those who have the official key, even if there are shaded workarounds. Brute
forcing sounds daunting to me: I guess we're not only dealing with proprietary
AT commands, but with a sequence as well.

Well, there was no "I'm no kernel-dummy"-agreement when I ordered mine, just
the warning. Time to start building expertise, but lacking time as well (other
languages got different words for points in time and periods of time ;-) )

Do your best!

Is it not because of different options used in different flavours of arm? I
remember reading that the situation was improving, but if someone with more
actual knowledge could elaborate: welcome!

I thought I had some questions, but between starting to write and being
interrupted far too often by children running around, they slipped my mind.
Once again: keep up the good work and thanks for the update!
PS: I received some openmoko-list-messages, so I added them as a receipient in
case the servers are up again.
