Anyone have any issues updating their iPhone 4 to the latest firmware 4.0.1? I kept getting this error from iTunes: "The iPhone cannot be updated at this time because the iPhone software update server could not be contacted or is temporarily unavailable." I tried restarting my Mac. unplugging my iphone4...Switch on/off iPhone... Checked on my Firewall settings...still the same issue. Tried downloading the OS4.0.1 separately and use "Option+Restore in iTunes to restore but still the same issue... Any idea what should I do? P/S: Swapped my iPhone 4 in Apple Store due to camera producing Blue-ish spot in the middle. Hence, I setup my new iphone 4 restoring the backups from my previous iphone 4 settings.
