Thaks to all replies! I think i know what is it all about:

Dogus,
M3Gate is not supported by MMIT. You'll never get some result with it (beleive me). Try some of those:

Nokia MIT and Jataayu work on my PC (after Device Update 2!). But they get XHTML, not WML result. That's not bad, if you don't have a specific WML task.
I managed to open the first page with Ericsson R380 emulator with WML. But you must publish the wap service on external, real server (not behind firewall)

Rgds,
Yavor

Thanks for your help Yavor,

Be sure that I'll tell, If I happen to find a way to make it work.

In the end, I could view my page in openwave 4.1.1 on my local machine
MMIT returns wml to this emulator.

Also there is an article named "Integrating Openwave Simulators with Microsoft Visual Studio .NET" in msdn
