I am running Mac OSX 10.6.8, iTunes 10.5b43 (43), and have the new iOS 5 Beta 2 ipsw. I Option click on restore, select the ipsw, and get an error that says "The iPhone "Myname of my iphone" could not be updated. An unknown error occurred (3002)" any ideas how to fix this? And yes, my UDID is registered. iPhone 4 (AT&T) ...GSM Another note: Currently have iOS 5.0 Beta (1) installed. That installed without any issues. I then downloaded the new version of iTunes, installed it, rebooted, downloaded the new ios5 ipsw, and option clicked on restore.. it extracts once it's done extracting I get that error message.
