I have successfully jailbroken 1.1.3 using the dev team method. However, Installer does not successfully install anything that I have tried it with. At first, I would get a "main script execution failure", but I employed the fix that is on the Featured page of Installer: cd /Applications chmod -s Installer.app/Installer chown -R Installer.app This fixed my first problem. But now, I have a new one; half way through installing an application, Installer will crash. Does anyone know how to fix this?
