Offtopic: Yesterday I posted about the 1.1.2 Lockdownd patch and how there were a million different patches floating around. Seems the one from iPhone Elite team isn't foolproof (see the note by zibree). :)
1.1.2 Lockdownd PatcherBut if you're willing to take the risk anyway, you can download and compile patcher for v1.1.2 lockdownd by the iPhone Elite Team. Yes, you read it right, you need to compile it because the file is the source code of patcher in C. :)
The Patcher runs on both your PC and iPhone. Instructions on its usage can be found at the Patcher wiki.
