I bought my iPhone and it had software 1.0.2 on it. I then upgraded to software 1.1.1 when it was released. Today I tried to downgrade to software 1.0.2 but after a good 40 tries I gave up because I kept getting the iPhone “iPhone” could not be restored. An unknown error occured (1). I did it in the black screen restore mode and the iTunes logo + cable restore mode and nothing works. Any help would be greatly appreciated ! Thank you.
