Do not install it and make sure to uninstall it before installing Jailbreak 3.1.
Please use version 0.2 uninstaller even if you originally installed version 0.1.
Now yifanlu is recommending using this hack if you are using his hack with version >= 0.4 (he no longer provides this functionality).
It will still conflict with earlier yifanlu jail breaks, and with NiLuJe's jail breaks.
