Before i updated to iOS 4.0, i saved my 3.1.3 SHSH blobs. I am sick of this 4.0 crap, I didn't get any of the features i was promised. I've tried downgrading back to 3.1.3 because everyone says if you put it in DFU mode you can downgrade a MC model. Every time I have tried to downgrade, i get error message 1601? Is there a place i go to get my SHSH blobs back? Or is there a different way to downgrade?
