ok... so i did everuthing "by the book", but, it seams that it didn't install a "dummy network" on n900... :P
anyhow, and the connection switcher started to act wierd, and my phone started to act the same (and slowed 200%...) so i uninstaled all apps needed for that,... i will try to do that some other time, but will shure tell you if i manage to do on Win
thank you for reply BJ!
