I would agree that GSM will be not the field for "software radio", and also the AGPS chip, costs about 5 US-$ will be much more powerfull and have internal know how that an open software radio can't compete. > My original question remains: Why do this with a _phone_?

What is it's "mainline function"? I think it will be MObile KOmmunikation. During we hope that the phone will have Bluetooth (or Wi-Fi) WiMax is starting: http://en.wikipedia.org/wiki/Wimax And beside Bluetooth will be there RFID, PMR (446.0-446.1), DMR(446.1-446.2), DECT (also data transmission via DECT) There are many standards for mobile communication, instead of buying new hardware, software could make the other protcols usable for you - even for a hardwaresolution "software radio" to avoid having 3-4 tranceivers on a circuit board (Wi-Fi, Bluetooth, DECT, FM, AM, PMR...) Some of this channels could give us *maybe* data broadcast for assisted GPS for free (some day). So it belongs to the Neos mainline function. Such a FPGA in central position on the circuit board would change the design to massive - so this idea would be something for v2 or later. But... with a FPGA on the board of v1 (or selfsoldered solution) could let the development starts with the v1.
