1.0 1.0.1 1.0.2 1.1.1 1.1.2 1.1.3 1.1.4 ^ 1.1.1 and up supported by iPhone AND iPod Touch. Version 1.0.2 and below MIGHT work on iPod Touch but DO work on iPhone. I will update this thread whenever new firmware comes out. EDIT: I know there are already some of these but this is a GUARANTEED link up same day as release. If you have 2.0 BETA and iTunes says you have the latest version when 2.0 goes public, you can come here and shift restore or shift upgrade/check for update.
