I'm currently on the most recent beta build of iOS 5, and I'd like to downgrade back to the latest 4.XX build. As far as I can see, I should just be able to download the latest 4.XX build and option-click restore to it since it's still signed, but does anyone have an idea what will happen with my backups? Will I be able to restore from one of the backups from iOS 5, or is my only option to pretty much set up as new? Any ideas? Thank you in advance for your help!
