Downgrade firmware on iPhone to 2.2.0
Posted on 2009-02-18
I have an iPhone that was Jailbroken, unlocked, and mistakenly upgraded by a co-worker to firmware 2.2.1. Can anyone tell me if it is possible (and if so how?) to downgrade firmware back to 2.2.0?
Original question remains however if anyone has been successful at Jailbreaking the 2.2.1 firmware and could post the process of getting this done I will award points upon successfully completing that as well.
