Thanks
(but I still think it deserves a "howto" on the wiki)
This log is what I get when I install the version 3.5 of the sonyprst1homescreen,and try to change the displayed collections in the home preference menu.
The main errors I see are related to the sql queries and some /data/data/uk.co.droidinactu.sony.prst1.home/shared_prefs/uk.co.droidinactu.sony.prst1.home_preferences.xml file which seems to be missing.
(I attached the whole log file in case I am missing something...)
