Error 1638 - iPhone software update server can not be contacted.

Hi,


I can't update my iPhone iOS to 4.3.3 with iTunes since a few months i still have the 4.3 version. I am using iTunes with an iMac with all software updated.

I am getting the error "iPhone software update server can not be contacted..."


I made a few research and tried the following fix:

  1. http://support.apple.com/kb/TS1275 for error 1638 > 1004
  2. http://support.apple.com/kb/TS3297 with no success (specifically the Blocked by configuration section - 2 Rebuild network information, the hosts file under /private/etc/hosts had no information that needed to be commented with #)
  3. After all troubleshooting I re-installed iTunes with http://support.apple.com/kb/ht1224

And I am still getting the same error...


What can I do?


Thanks for your help

Same issue still with OS X Lion, last version of iTunes, can't update to iOS 4.3.5 or restore my iPhone 4. iPhone isn't Jailbrake. I am allways getting the error: "the iPhone "****" cannot be updated at this time because the iPhone software update server could not be contacted or is temporarily unavailable." (error 1638).


I'd like to update iOS or restore my iPhone if needed but this doesn't seem to work neither as the problem is related to the conenction to the server.


Can anyone help?
