I'm not an gnokii developer, but I know the Nokia mobile phones very well 
(I've written an commercial app under Windows - see Cellular Essentials at 
www.demmel.com ). Using Obex should not be the big problem as there is e.g. 
OpenOBEX for Linux out there, but the problem I see is as follows (already 
stated in a previous mail, but nobody mentioned it):

Obex / Symbian is a rather file I/O based thing, so I assume there will be 
no major problem to read / write the phone book file (in fact the phone 
book is a file laying on the 7650) and other things like pictures. But I 
assume it will be very, very difficult to e.g. let the 7650 send an SMS. 
And I do not know ANY program which is capable to do this (Nokia's PC Suite 
for the 7650 only supports file I/O transfers) so there is no possibilty to 
spy into an application's traffic. I know that there is a commercial 
program in the stores for the 7650 and this program has a very different 
approach: They upload a small application to the phone and this application 
does the communication with the PC program and controls the 7650 as well (I 
think sending a SMS via the local program on the 7650 can be done rather 
easy as these things seem to be documented).

So I assume it will be very much work to make the 7650 working. This is the 
reason why I did not start with this work for my program although it 
supports 40 different Nokia phones. My estimation was about a 1/2 man year 
work and this was too much.

Please do not understand me in the wrong way: I do NOT want you to 
demotivate, but you should see the problems which can arrive before you 
start the work.

From now on I will shut up and not disturbe your discussions anymore.
