[Gta04-owner] Invitation to indicate interest in next batch of GTA04A5 boards

Hello Nikolaus,

some concrete recommendations for GD, resulting out of my explanations:

a) Design the plate of the GTA04A5 so, that the variant that is equipped 
with B2B connectors instead of display also has one further connector 
instead of the modem.

b) Make a little board equipped with the modem so, that it can be 
connected to the modem connector of this GTA04A5.

c) Offer the handheld variant of the GTA04 ("OpenPhoenux 3704") in this 
way. There should be enough place within the case in order to do so.

d) In any case where you advertise the GTA04A5, never forget to mention 
that it is intended to develop the gravity to attact a new community of 
developers, who replace your little modem board by a self-made one, 
equipped with a new open source LTE modem.

e) Also never forget to express the dream, that then this device would 
have the potential to develop the gravity to also attract a community of 
developers, who write the open source firmware for it. If this dream 
would come true, then place the offer that GD is willing to take the 
results to create a GTA05 out of them, to get the needed certificates 
and in the end: To sell it to everyone who wants to have it.

f) Never forget to argue, how good the initial situation for such a 
project is: GTA04A4 equipped with QtMoko v55 should be convincing, that 
a very big amount of work to get such a new GTA05 phone has already been 

Best regards
