Awesome and very interesting. Can't wait to see PoF "real world" usage tests (i.e. using such setup - probably, with better antenna 
as substitute of x or y separate hardware - as PoF, without ergonomic optimizations).

Well, i hope someone would start trying this kind of setup, sharing opinions and experiences......Maybe also posting here some gnuradio grc file like these examples:
http://superkuh.com/rtlsdr.html
or...why not ...a next generation GNSS positioning system receiver!
http://www.gnss-sdr.org/documentatio...dvb-t-receiver
or...receive NOAA images:
http://www.oz9aec.net/index.php/gnu-...ongle-and-gqrx
We need any feedback/ideas because this could help to do the right choices while engineering .....the new Neo900!

Xes, projects like this and fldigi are great, and I mean kick@$$ great. The only issue is if you don't send them up to the unstable repos it means that installing and more importantly uninstalling is a super pain unless we take great notes and are sure to clean up our mess when the next version comes out. Even providing the bins with a make install/uniststall would help though I think at that point pushing out a .deb might be easier.
Thanks again for the uber cool work.

But i haven't much free time to prepare debs in a proper way.
Prepare a few deb files that with an automated procedure could damage your system because i have no much time to check how they are working in all situations... is really worst than force who wants to try to use his mind to double check what he is doing.
When all this will be stable and considered useful for the community, i would spend some time to package all the required files.

OH,this is very cool ,
is it possible to let osmocomBB run on n900?

You at least would need a means to switch off and bypass the converter, and unless you do that with a slide switch on the dongle, there's probably no way to do it via USB.
For hams and those who follow HF bands there is this downconverter kit
http://www.easy-kits.com/rtlsdr-for-...onverter-rev-4
It fits inside the dongle enclosure!
This is the Smallest all-band HF receiver in the world, now for the N900.
Did I miss something? Did they find a cute way to control the converter e.g. via the IR, LED or other GPIO on rtl2832? Or would I actually need two of those for the full range?

osmocomBB devided into two separate applications:
1,running on the baseband chip of the phone
2,running on a PC, communicating with the baseband firmware over serial
i mean is possible use n900 instead of PC host ,connect "compatible phone" (@@MotorolaC115@@) to N900 via H-E-N hostmode,MotorolaC115. MotorolaC115 run osmocomBB baseband firmware ,and N900 run Firmware management and GSM Layer 2/3 application
sorry ,my bad english ..
