Further digging reveals that the driver for the GPS hardware has been written so that it presents itself as a network interface (phonet0) rather than a block device.

Given that all GPS hardware I have ever seen is accessed via a serial or usb device, does anyone know why this architectural decision was made?

Can any Nokia techs tell me if it is possible for me to write a block device driver for the GPS hardware? I'd like to present it as /dev/gps for ease of use....
