I'm writing in regard to the ability to dual-boot the Android OS and iPhone OS with the iPhoDroid program. I noticed that it only worked on the iPhone 3G, which I have, and that it be jailbroken with redsn0w.
I have already jailbroken the device with jailbreakme.com, so I need to restore it back to 4.0. I downloaded FW 4.0 and attempted to restore it, however iTunes (10) will not authorize the restore/update to continue. I'm having a tough time trying to figure out how I may circumvent this error in order to re-jailbreak my iPhone.
If you have any solutions to offer, I'd appreciate it.
