DTResurrectionKit currently saves its state based data in /Documents/DTResurrectionKit. The problem is that this folder will be visible to the user when using the UIFileSharingEnabled in the Info.plist.
The data should probably be saved in /Library/DTResurrectionKit, to make sure it will not be seen by the user. It will also still be preserved when iTunes backs the device up or restores it.
