Sorry to be so annoying, but it didn't work
I have the applications.zip found on a 4share link on mobileread, that contains the applications/qorganizer/etc.... folders
I copied the zip file to the root directory, went to it through the cd you said, and tried unzipping.
I get
Code:
creating: applications/qorganizer/
unzip: can't set permissions of directory 'applications/qorganizer/': Operation not permitted
unzip: exiting
another thing, although probably not related.
I copied the pbanki/mindcraft0.2.8 app to the applications folder as well, since I would like to use flashcards, but this applications doesn't work as well.
Anyhow the russian tank war game, which I also installed, works.
