I've always wondered but never really tried since it always slips my mind. Would it be possible to restore an idevice to the same iOS with the blobs for that iOS after the signing period has ended? I.E. if you're running 5.1.1 now, and only 6.0 is being signed, would you be able to restore it back to 5.1.1 as in a clean install using blobs? I know that you'd need Pwned DFU for downgrading but would regular DFU work for basically "re-installing" an iOS? On non-A5 devices, you would be able to upgrade them to 6.0 then downgrade again with RedSn0w or sn0wbreeze with the low level boot exploit, but would it work on A5s?
