Go into settings and sign out of the app store.
Put your phone in airplane mode.
Reset your phone by holding down the power button and home button simultaneously until it restarts.
Hook up with iTunes and proceed with update.
AIRPLANE MODE
Airplane mode worked for me on the first try.
I tried about a dozen times before.
Thanks!!!!
I'm trying to update my Verizon iPhone 4 to iOS 5 and I keep getting the error message too. Now, I'm getting a more detailed one "The iPhone ... could not be restored. This device isn't eligible for the requested build."
HELP!

Has anyone tried updating the security first, then upgrading to iOS5?

There's is NO QUICK FIX. It's whether or not you make it in the query line for updating. People keep posting all these little things like spinning in their chair 3 times and hitting airplane mode.
It doesn't matter. It's luck.
Tried Airplane mode and didn't work for it. Airplane has nothing to do with it- it's just luck and getting the right spot at the right time. I've nearing 40 tries and lost all my iPhone backups, etc and I still haven't made it through the error.
Apple just did this WORLDWIDE update involving every iPhone hooked up to iTunes.... at the same minute. Stupidest thing I've ever seen from Apple. Laughably poor planning.
