First, you must on a successfully JailBroken 1.1.2 device and have BSD Subsystem 1.5 or later installed. However, a full restore is recommended for best results. Once you are ready to upgrade to software 1.1.3: Install Upgrade.app onto your iPod/iPhone: either via SSH or directly from Installer "Official 1.1.3 Upgrader". Set the permissions (only if installed manually). Respring. Run the app from the iPod/iPhone. Don't want to manually add this to your iPod? Wait. It will be available in Installer soon. Big thanks go out to planetbeing and the rest of the Dev Team. EDIT: It's Official. It has a GUI. It fixes the size of the root partition. Sets it back to 300MB. If, after upgrading, you can't listen to music, or watch videos, then you will need to reset your settings. Settings -> General -> Reset -> Reset All Settings Your may need to run the reset twice.
