I decided to try my iPad first and got this as well. I deleted the .IPSW file and tried again to know avail. I'm going to try the iPod now and see if that will go. I'd like to get it working on one other device before doing my iPhone..
I'm getting it too. I have reinstalled iTunes, rebooted computer, rebooted iPhone, and continue to get this error message. Getting ticked off. Anyone know how to resolve this?
where is it documented that it is a server overload? Whats gonna happen tonight after we all get off work and tring to update. Surely Apple has planned for this.
