    My iPhone 4 isn't jailbroken or anything, but i can't update it, i've tried restoring but i keep getting the same message:

    "The iPhone "xxxx" could not be updated. This device isn't eligible for the request build."

    Do you have a good backup. You can try a DFU mode restore.

    Your virus checker / firewall may be blocking the activation server or the hosts file could be. Have you ever used TinyUmbrella?

    Check your hosts file

    On Mac, open terminal app, type the following without quotes "more /etc/hosts"
    If there are lines that mention apple.com, you will need to edit them out.

    On windows its under C:/windows/system32/drivers/etc/hosts

    It added entries to your hosts files. Delete the entries, (use link I posted) and that should fix it.
