damaged my nokia6610 using gnokii with CA-42 cable?

[Stephan Maseizik]

I have got a serious problem with my Nokia 6610 which is not working
any more. What happened? 
I bought a CA-42 remake cable that is recognised as a Prolific PL-2303
in debian unstable (debian kernel 2.6.12-1-k7). I installed 
gnokii_0.6.8-0.2_i386.deb and gnokii-smsd_0.6.8-0.2_i386.deb, copied 
/etc/.gnokiirc to my home directory and only changed port = /dev/ttyS0
to port = /dev/ttyUSB0 and model = 6510 to model = 6610.
I then started xgnokii from the konsole. First time, no connection.
Second try the program connected and I was able to read my entries and
save them to disk. I played around a bit, made a new entry in the
phone book and even in the calender. I had a look at the SMS menu and
then at the configuration menu. There the phone was listed as
72_something, which I tried to change to 6610. 
In the konsole I saw a few error messages:
---------------------
Gtk-CRITICAL **: file gtkentry.c: line 440 (gtk_entry_set_text):
assertion `text != NULL' failed.
Event 22 failed with return code 6!

Gtk-CRITICAL **: file gtkentry.c: line 440 (gtk_entry_set_text):
assertion `text != NULL' failed.
-----------------------
I killed xgnokii and now my mobile phone seems to be broken. I can
press on/off to power on the phone and enter the pin which is accepted.
After that there is no nokia logo as there used to be and the
backlights go off immediately. After pressing some buttons the phone
powers off completly! When I take out the SIM-card the phone askes for
a SIM-card (normal behavior). 
Did I break my phone? Did I damage my SIM-card? What can I do? Is it
save to test a second SIM-card of a friend using my phone or could I
damage his card?

Ideas, help and advice are most welcome! Please help!

P.S.: After all that happened I read "Good to know about PL2303" from 
BORBELY Zolt] in this newsgroup and tested my cable using 
lsusb -v -d 067b:2303. bMaxPacketSize0  is 64, so I probably have a
PL-2303X cable. Do I need a patch?
