Someone (not clear who) said:
[...] The calypso is just to outdated to be interesting for anything 'useable' beyond pure hacking-fun.
I violently disagree with that statement. I personally carry a cellphone for one and only one purpose: so I can call my significant other (soon to be wife) and she can cell me at any time. A handset based on the Calypso chipset does this job wonderfully, and is IMO the optimal tool for the job.
But the problem is that at the present time there does not exist any cellphone at all, of any kind (dumb, smart, old, new, whatever) that can make and receive cellular phone calls using only Free Software, as defined by the Free Software Foundation, i.e., providing the user with the most essential Four Freedoms:
http://www.gnu.org/philosophy/free-sw.html
Hence I am currently forced to use a cellphone that runs proprietary firmware, such that I lack the ability to fix any of the UI design flaws that constantly drive me nuts. This situation causes me severe distress, hence I have committed my hobby time and cash budget to a multi-year project to solve this pressing (for me) problem.
OsmocomBB is not a solution: it works wonders for "hacking-fun" (the wording in the comment I'm responding to), but is utterly useless for a practical phone which one can carry around in a pocket or purse: my back just isn't strong enough to carry a supersized backpack containing a full PC for running the L23 stack plus a bank of lead-acid batteries. Hence I need a totally different Free Software GSM handset implementation, one that actually runs on the phone itself with proper power management exactly like the original proprietary firmware. And because no one else is working on such a thing, I started my own, and made quite a bit of progress:
https://bitbucket.org/falconian/freecalypso-sw
But I am using the same Calypso GSM chipset for my project as OsmocomBB uses, simply because it is IMO the optimal tool for the job at hand: allowing a person to communicate with his or her significant other by way of cellular phone calls. The word "outdated" does not exist in my vocabulary; I evaluate a tool based on how well it does the job, rather than some arbitrary irrelevant criteria like manufacture date stamps or whatever.

I think this desire is recognized. I remember an initiative some years back, started with some enthusiasm, that never got passed the stage of deciding on NuttX as the OS to use, and forking it.

I don't quite see how waving the Free Software flag and distributing proprietary source from the TSM30/Locosto leaks (pretty much everything in freecalypso-sw/gsm-fw/) go together. Your efforts would be of much more use if you based them on top of osmocom-bb itself.
As long as this main issue with your project remains, I kindly ask you to refrain from making false claims and further advertising your project on this list.
Best Regards, Steve
Pleae, then tell me where to get phones with a Calypso baseband. And I'm talking about marked relevant prices. Don't waste my time with numbers like 5000$.
And to be relevant these phones must still be produced so I can get many, if I want.
Do you know a source?
Beside, I think its better to work on reverse engineered GSM stacks like the Qualcom project as started in
https://events.ccc.de/congress/2011/Fahrplan/events/4735.en.html
This would capture a lot of phones, since it seems they use more or less the same real-time GSM-OS in most (all?) of their products.
