I am attempting to do a 3rd gen 3.1.2 32gb jailbreak for my friend. I am aware that first i need to downgrade from 3.1.3 to 3.1.2. When i go to downgrade (Shift+Restore+Pick firmware from desktop) It tells me that my device isn't eligible for the requested build. Please help me. I dont even know if there is a 3rd gen jailbreak out. Help me please, thanks.
