I've set my reader shared prefs file to mode 664, and then changed the default font size and that at least didn't reset the permissions. I'll see if it sticks or gets reset at some stage.
The sledgehammer would be for your app to run as root but that does seem like overkill.
Off topic - there's a pref in the xml called SpreadDirection, set to 0. Does that make any sense to anyone?
Does the modified Reader use the default font size after you set the permissions?
