>Somehow it was able to boot again. Don't know why.
I see, you have Diablo (because of Modest). I suspect Diablo in booting fault (I even had to reflash it).


>/etc/n800-s2ram.cfg says '1'
- it means that daemon watching when you lock the device. It is convenient to shortcut n800-s2ran-start / n800-s2ran-start commands, they change 1/0 in /etc/n800-s2ram.cfg

>I can unlock it but this doesn't function. Tapping does nothing.
What do you mean? Ping doesn't continue? Or touchscreen is not react? I unlock in usual way (power button, then joystick button which mapped as <space>) and touchscreen works.

>...because it doesn't have a network connection.
Yes, I see that connection sometimes does not re-enabled automatically. I just enable it "by hands". I'll find out how to send d-bus messages to re-enable connection.

>The ambient light is still blinking (maybe it should be put off, or make be red for this current state?).
On my N800 it stops to blink. So, I even didn't think about it.Well, I'll put a chunk of code to disable blinking.

And the last one. Did you locked it for more than one minute? Because I kick a watchdog every minute lest it will shutdown NIT. On my n800 watchdog kicked properly, and it slept for day and night.
