I am also a newbie in Linux and I too have easy debian in my mobile. If you are able to see swirl for that hide UA file, then app. manger should start automatically(you dont have to select which application to open that file). follow these steps now, 1)delete that file 2)click this link and save the file in any other folder. http://repository.maemo.org/extras-t....3.7_armel.deb 3)open file manager and browse through that folder and click the .deb file(swirl icon).Now, it should start the app. manager automatically,like the way how media player starts when you click on a .mp3 file.
