exchanging notes between a Siemens & a Nokia, via bluetooth. How?

Hi all!

The following: I'm trying to exchange notes between a Siemens S65 & a
newer model Nokia, via bluetooth.

Noka -> Siemens works fine. The Siemens receives a file called
Nokia.txt, containing the text.

Siemens -> Nokia does not work. The Nokia complains that it can't handle
the file format.


Is there any way to get this to work?
