Are you familiar with the terminal? If so, do this: 1. Uninstall firefox 1.0.1 2. Download newest beta fennec_1.1.somethingsomething_armel.deb 3. Go to terminal and become root 4. Install with dpkg -i fennec_1.1.somethingsomething_armel.deb (You have to be in the correct directory when you install it - but you know how to do that, if you're familiar with the terminal). I did this today and it works. You can't get the wrong version if you download the right version and install it with dpkg.
