Workaround to Fix Error 3002, 1604, 1600 During iOS 5 Restore – iOS 5 beta 1 (iOS5b1) .ipsw files have been leaked for download and install.

1- Install newest version of iTunes while do not connect your iPhone, iPod or iPad yet.
2- Once installed, run new iTunes for a while then close it.

C:\Documents and Settings\Application Data\Apple Computer\iTunes\iPhone Software Updates
Mac users need to locate it. I don’t really sure where it is.

Do not delete them in case the steps does not work for you, you can still copy them back to the folder. You can find out your username by pressing Ctrl+Alt+Del.
