I did the 2.0.1 update, spent the last hour letting my 1st gen iPhone back up all appeared to go well. Then it did the "preparing to install" BS and so forth. I was struck with the Cannot Update iPhone error 1602. It told me to restore, etc etc, so I did. I was given the "Cannot Restore error 1604". I have the latest version of iTunes. I'm unsure where to go from here. I did the uninstall of itunes and such as directed by this forum and Apple support as well. Any other thoughts? The phone was no jailbroken or unlocked. I had nothing custom on it, just some apps I either downloaded or purchased.
