Hi Nicolas,

I've also tried to hack a little with the fwtftpd today to serve the cfg.txt
to the phones (and also updates to software). I cannot get it to accept the
cfg.txt i give it though - have anyone successfully served that file to
their GS phone? or made it update the firmware with fwtftpd?
I made a updated fwftpd.java file - anyone is welcome to test it here:
http://musimi.dk/fwtftpd.java
it uses the mac address of the GS phone and then sends the /cfg/{MAC}.txt
file when the phone requests the cfg.txt
Please help with getting the phone to accept the config file? - should i
send something back as OptionsACK to show the GS phone that it is ok to
update?

Cheers,
