By user store I mean the FAT partition accessible from Windows over USB.
It contains the
documents folder as well.
You should be able to find these folders there:
Code:
.active-content-data
audible
documents
music
system
keyboard
linkjail
Folders in
bold are those contained in userstore.zip - you need to copy them to user store (+reboot) to make jailbreak & physkeyb actually work.
