nokia 5200, can't send address book

[Nicoco Kinlidex]

Hi !

I'm experiencing problems synchronizing my PC Adress with my nokia 5200

*My .gnokiirc :*
[global]
port = /dev/ttyACM0
model = AT
initlength = default
connection = serial

*kaddressbook log :*

*another test*
$ gnokii --writephonebook
gnokiid Version 0.6.14
test;012345678;ME;0;0
Erreur: Emplacement memoire SMS non valide.. ("SMS Memory slot not valid" in 
english)


Did I do something wrong ?
Does this phone implements phonebook sync differently ?

If there's a way I can help improving support for my mobile, tell me what I 
can do !

Thanks for your work.
