To go into detail the situation is this:

In addition to the naked motherboard these parts from a GTA01/02 are reused:
a) case (3 black plastic parts plus white speaker box)
b) vibramotor
c) earpiece speaker
d) handsfree/music speaker(s)
e) display panel
f) battery
g) GSM antenna
h) active GPS antenna module

Replacements are
a) there are several STL designs available, even a wooden case looks feasible.
b) we will solder a small(er) vibramotor on the GTA04A5 board, so that it does not longer need to be reused.
c) here, we did have a replacement but it is now end of life. We have a supplier and catalog for other replacements.
d) they were easily available at Mouser until last summer. So we just have ~25 pieces left over [1]. But it could be possible to find them on Alibaba.
e) here we have ca. 60 units [2] - and no idea if anyone has stock for more.
f) we still have some stock and maybe other of the well known Openmoko distributors as well.
g) here we want to offer a replacement (similar to the green “cucumber” in the photo [3]).
h) there are several GPS modules to choose from.

So in summary, we already offer some of the required components and will offer others.
But three key components (battery, handsfree speakers and display) are limited and w/o good replacments.
