GNUBox is a freeware application for Nokia S60 mobile devices that allows you to connect to the internet on your moble device using your desktop computer’s internet connection through Bluetooth or USB.
Till now, there was a version available only for S60 v1, 2 and Sony Ericsson UIQ 2 based mobile devices. Now it has been ported to the S60 3rd Edition platform for Nokia N80, N95 or any NSeries/ESeries device using Python for S60. You can download an unsigned version of the utility here
I have no idea as to how this works since mRouter is no longer used/available. So if anyone has gotten this to work, please let me know!
