Wait for the blinking "!" in status bar, do a backup(!), click on the blicking "!", click on the associated status menu button, watch HAM open up and show "Maemo 5 Community SSU update", click "update all", click thru the dialog that appears, watch 25min of download and update, followed by a reboot.
@all who want CSSU installation to be supported trough FAM - it won't happen. HAM supports functionality focused on firmware updates while FAM and apt-get don't. And it does not make sense CSSU deves/maintainers to test every software out there that could be used to install some packages.
On the other hand I know joerg hates HAM. You can think for a while why then he insist you to use it for the CSSU updates. Maybe then you will stop bloating this thread further with stupid question/requirements.
flavor Testing!!!
