Ok, checking the code, I've seen that this part I had it already with
"#if 0". I have done a couple of tests, and I've seen that rild is
correctly getting the /dev/tty device. If I send AT commands with my
tool, and then I "kill <rild_pid>", I see distinct strings on "logcat
-b radio", so rild is working... Thanks for the tip :)
But my real problem is still there... When the UI starts, I'm seeing
fake info (it says that I'm in roaming and data connected with Edge).
This is simply not possible (using a SIM card from my own country,
which doesn't support EDGE anywhere :P).
Maybe my problem is with the "/dev/socket/rild" and
"/dev/socket/rild-debug"?. Doing a "ls -l /dev/socket/", rild is a
socket, with 660 permissions for root:radio, and rild-debug is a
socket with 660 permissions for radio:system (as it is specified on
init.rc)
What part of android tries to use them, and what does it do when
something doesn't work?

Nice :) But I would like to connect with the USB dongle configuring up
the network device. In case this would be impossible, then I'll try
with ppp. Thanks for pointing this other bit

Not really, but I'm pretty close ;)
Thanks and kind regards,
