Hey.
I was looking for a tool to sync iTunes with my Nokia N80. I have 2gb Space on the Nokia, so why not?

And I found a tool to sync nearly everything with iTunes.

To use it with your Nokia, and you want to have the songs in /Sounds/Digital you have to change the code [MassStorSyncNokia.bat]:

from this:
if exist "C%MSDNokia%" set MSDPath=C:
if exist "D%MSDNokia%" set MSDPath=D:
if exist "E%MSDNokia%" set MSDPath=E:
...
to this:
if exist "C%MSDNokia%" set MSDPath=C:/Sounds/Digital
if exist "D%MSDNokia%" set MSDPath=D:/Sounds/Digital
if exist "E%MSDNokia%" set MSDPath=E:/Sounds/Digital
...

have fun!
