Over the last weeks, Dieter has made some great progress with getting
the new firmware into shape, and we'll have a public update soon. We
expect the next version to fix bug #666 and it will also have a new
command AT+CSIM.

Our plan for the upgrade process is to make a self-contained update
image that can be copied to a uSD card, then boots from there, and has
a simple GUI to kick off the upgrade. That way, we have an environment
that's entirely under our control and we don't risk conflicts with
other services trying to access GSM or the like while we're in the
middle of an update.

I'm making the run-time environment, based on myroot. Then Joerg and
Dieter will fill in the blanks with the actual firmware handling,
FLUID invocation and such.

My current set of wrapper scripts, for dry-running on the host, is in

See README for details.

The actual run-time environment for the Neo will follow in a bit.
