    I had an iPhone 3GS jailbreaked and unlocked. However I bought a new iPhone 5 a couple of weeks ago,
    when activated it automatically came with iOS6.0 but ever since then i've not been able to upgrade the iOS any further.
    Last message I got was "error 3004" when trying to install iOS7.0. Note that this is not a jailbreaked phone, though
    I did make a full restore and backup from my last iPhone that was jailbreaked, dont know if this makes any difference?
    Anyone had the same experience? How can I solve this?

    Thanks alot for thoughts and replies!!!

    Your computer's Hosts file needs to have entries removed from it for the host gs.apple.com - fix your host file, reboot the computer - and you should be able to update via iTunes fine.
