I upgraded tot 1.1.3 wiht Nate's method after the day he published it.
I don't remember this before, but as of today my iPhone seems to freeze sometimes, randomly. Also I've been having freezes when I refreshed installer sources, and my network settings don't save anymore.
So I was thinking of going back to the good old 1.1.2. I've searched the forums but I didn't find anything sure or specific. Is there a 100% safe way to downgrade?
