You can already get the Telit GM862-GPS GSM Modem w/ GPS, along with the Bluetooth/WiFi module, thats four networks in two packages, with open specs and existing project plans for Linux. the fun part is going to be figuring out how to lay out four antennas in a small package.
The OpenCell project http://www.widgetry.org/dokuwiki/doku.php?id=parts_lists is trailblazing this particular combination. And of course, anything the homebrew designs work out is openly documented so could be evaluated by the OpenMoko team for future designs that might actually fit in your pocket....

Basically - perhaps at some time in the distant future. For the moment, basically no. There are a large number of reasons why not - firstly, 1GHz A/D converter chips are both large, power-hungry, and expensive. Secondly, processing the output from them is hard. Thirdly, the dynamic range and intermodulation between different radio frequencies mean that it's even harder. _______________________________________________ OpenMoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
