I'm trying to upgrade my iPhone 3GS to iOS 5, but obtain error code 1654 unable to restore the iPhone. What does that mean, what do I do?

iPhone 3GS, iOS 4.3.3

    Hi, not sure what causes it but if you


    1. do a full back up in itunes (right-click on your device in the sidebar and choose backup) and then
    2. choose "restore" rather than "update" in itunes you'll get the option to
    3. restore your device from your backup.


    It takes way longer, of course, but it works.


    Good luck.

    I found a very simple fix, which has worked for me and others:


    * Disable sync over Wi-Fi, then attempt the upgrade again.
