Ok.  So if there was to be a free-as-in-freedom Galaxy Nexus, with full 
control of all layers, it would be the result of a real, material breech, 
or leak.  Someone would have to do Something Bad.

But the point here is an end user (like me) having a secure and 
free-as-in-freedom phone, so unless we're going to create a 
community-backed reference platform (which would be great, of course) this 
doesn't help a lot.  Are there any 3G handsets currently for sale that 
have this (more open) system underneath ?

You're approaching this as if I want to build and market cell site 
equipment, or build my own infrastructure ... of course that is 
interesting, but really all I want is a somewhat modern phone that I can 
control and feel somewhat secure in using, which means either isolataing 
the basebadn processor (see my other thread about using USB GSM modems 
with a galaxy music player) or breaking the baseband of a platform more 
useful than calypso...

I do wonder, however, if these open reference chipsets exist, why we are 
looking at calypso as the basis for the "other" osmocom projects (like the 
baseband dev kit that has been proposed...) it seems like your example 
would be less of a dead end...
