I downgraded to 1.1.1 from 1.1.2 earlier today. I followed all of the steps to jailbreak my touch using this tutorial : http://www.youtube.com/watch?v=nLjab_dmWCg, from ipodtouchmaster. Here is where is got into a little trouble. When it came time to update the installer. I noticed that on the tutorial, it showed "Installer Version 3.0b3". I noticed that on my touch it showed "Installer Version 3.0b8". I attempted to update the installer. I received the message "Error, Package file size mismatch". What should my next move be?
