I am in a very difficult situation.My ipad I have now came with ios 4.3.5.So I said to myself "I won't need these blobs cause why would I want to go back to that anyway."And now I'm in a situation where I want to go back to 5.1.1 but can't cause I don't have the blobs saved from 4.3.5. Is there any way to downgrade on iTunes .and will there ever be a way to downgrade in the future without the ios 4 blobs?
