Siemens S55 and ISync

[Wolfram Jocks]

I've got a Siemens S55 which is a very nice phone. As it is nearly the 
same phone as Sony's T68 I thought it might be possible to use ISync 
with it. I have got a Blootooth USB Adapter and the phone is recognized 
by ISync but can not syncronize it with my Addressbook. Does anybody 
known if there is a way to link my S55 with my Mac Jaguar, German 
language?
Grateful for any hints.
