Thank you all for your answers.

Everything works great now, I choose desktop app, works fine, then Sybian or Maemo still fine. I am very glad. Much appreciated.

Let's say now though, you develop an application you want for Sybian. You test it and it works like a charm and you decide to "export" it. Is this the right way to say it? Anyway, what I am trying to say is that, you want to install it on your phone or even share on a forum or with friends.

How would you do that? Is there something additional to be done?
