I can see the TI being closed with the GSM firmware, because its illegal to release to the public, because people like me who would write a monitor driver for it, no that it would be terribly useful with Digital spread spectrum radio. The thing I am concerned with is when I bought my Neo no one know that the GSM 850 was busted and It looks like it will not be repaired. Also I am concerned with the GTA02, as of right now the wifi Firmware does not support monitor mode( http://article.gmane.org/gmane.comp.handhelds.openmoko.kernel/865 ). I am a Security tester and I *Must* have this function. Im sure the demand will facilitate the implementation of this function, but it should have been known that selling 'Hackers' phones for 'Hackers' would have required this function. I dont want to focus on the negative aspects of the soft/firmware because OM has treated us all well with the open technology movement. I am defiantly going to be a customer/developer for life.

'a little cpu-speed' is an assumption. The more open these chips are,
the more software's running on the CPU, the more CPU speed they'll
400MHz is really, *really* easy to use up. Considering how much stuff
the other ICs do by themselves, we can heavily load the CPU pretty
easily. Also, we can lose phone reliability, as the scheduling of
periodic tasks could be delayed by other things (do we even have a
hard real-time scheduler here?). IMHO it's a giant waste of CPU &
battery power -- the other chips will still be running, but now we're
using the CPU more.
For what? I don't think the GSM chip does anything terribly
interesting. Wifi's not much better, and the GPS is probably the
simplest. I'm sure others want to find that out themselves through
their own hacking. But I don't want to fill up my CPU with garbage
the other dedicated chips should be doing. If openmoko decides to go
through with this firmware opening, please give us a way to use the
regular firmware, too.
I have plans for that CPU.
