I currently own a 3.1.2 - Blackra1n'd ipod touch. Question 1: What are the current benefits from upgrading from 3.1.2 to 4.0 or 4.0.1? Question 2: When I tried to restore my ipod via the shift-click method, I got an error (3914)? Is there a workaround? Do I need to be in DFU/Safe mode or whatever? Or is it possible to upgrade to 4.0 straight from my jailbroken ipod touch?
