    Hello patmac0708,

    If I understand your question, you are trying to sync your iPhone 4S with your computer, but you are seeing an error message that indicates there is an "invalid response" from the iPhone, is that right?  Are you using a Windows PC?  If so, your security software may be blocking the connection.  

    Resolve issues between iTunes and security software - Apple Support
    http://support.apple.com/en-us/HT201413

    Get started

    First try these basic steps to see if they resolve the issue. If they don’t, continue to the next section. 

    •  Set the correct date, time, and time zone on your computer. 
    •  Log in to an administrative user account.
    •  Get the latest version of iTunes.
    •  Update OS X or Windows, and update your security software.

    Configure your software

    After you update your security software, configure it to let iTunes communicate through the ports and servers listed here. Configuration steps vary by software, so contact the developer for specifics. Blocked ports are often related to numbered errors in the 3000 range.

    • Ports: 80 and 443
    • Apple servers: 
      • phobos.apple.com
      • deimos3.apple.com
      • albert.apple.com
      • gs.apple.com
      • itunes.apple.com
      • ax.itunes.apple.com        
      • Verisign servers:
      • evintl-ocsp.verisign.com
      • evsecure-ocsp.verisign.com

    Find a more complete list of ports used by Apple products. You might also need to configure your security software to allow specific services to run. 

     

    Remove your software and proxies

    If your PC or router is using proxy settings, try connecting to the iTunes Store without using an Internet proxy. On a PC, you can use the built-in diagnostics in iTunes to test your connections and generate reports.

    If the issue continues, disable or uninstall your security software temporarily, but first note any licenses and confirm you can reinstall the software. 

    • Restart your computer and try to connect with iTunes again. 
    • Check your hosts file to verify that it's not blocking iTunes from communicating with the update server.

    When you’re done with these steps, re-install and re-enable your security software to keep your system safe. If uninstalling your security software resolved the issue, contact the developer to help you configure the software to work with iTunes.

     

    Hope this helps ...
