Prior to the update the tutorials required you to click the update button to install 1.1.2 on your iPhone. Now since 1.1.3 has been released simply clicking update will NOT work. You have to option/shift click the update button and select 1.1.2 ipsw file directly.
The tutorials have been modified so there is no concern with following them... and again... PLEASE DO NOT UPDATE TO 1.1.3 YET!
Thanks for your support!
