Modified firmware:
The code was never finished since easier and more maintainable solutions
exist. See below.

BASIC Stamp:
I believe that code was completed. The SMS encryption protocol (SEMS)
that grew out of that project has been published. SEMS has seen a bit of
review from the community; the protocol is sufficiently simple to
probably not hold any surprises. The protocol specs used to be at
http://www.nah6.com/SEMS 
Unfortunately, this part of the NAH6 website is currently down for
maintenance. I am told the site will be back up shortly.

In the end, firmware low-level hacks to enable SMS encryption were
obsoleted by Moore's Law. GSM smart phones/PDAs that run normal
applications are easy to obtain at a reasonable price.

Should you plan to write an SMS encryption application, you may wish to
remain compatible with SEMS -- and be it for no other reason that SEMS
has some non-zero deployed base.

Hope that helps,
