I followed the video and read the wiki page over and over.
I installed CSSU, pressed the icon. (now not listed in the menu anymore) When I try and 'update' CSSU, The Application details say..

Summary: this Maemo update requires Nokia PC Suite on your PC for installation. Connect device to PC via USB cable and open Nokia PC Suite. The application will guide you through the rest of the Maemo update.

Problems... Unable to update 'Maemo 5 Community SSU Package'. Conflict with application packages: libqt4-test (4.7.0-git20100909-0maemo1+0m5)

My Maemo5 version is 20.2010.36-2.002

Any suggestions? Please?
