Are you using a Mac or a PC?

You should always have the newest version of iTunes; downgrading will not affect that issue.

From this support document http://support.apple.com/kb/TS3694

iTunes cannot connect to the iPhone because an invalid response received from the device

This error occurs when there are problems communicating through USB. This may be resolved by following the steps for errors 13 or 14 above.

Error 13, 14, 35 and 50 (or -50)

These errors are typically resolved by performing one or more of the steps listed below:

Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
Put a USB 2.0 hub between the device and the computer.
Try a different USB 30-pin dock-connector cable.
Eliminate third-party security software conflicts.
There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.
Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
Try to restore from another known-good computer and network.

You need to have the latest version of iTunes to connect to iOS 7.0.3. What computer OS are you using? If Windows, then you will need to follow these directions exactly to remove iTunes and reinstall the new one. http://support.apple.com/kb/HT1923

Hi all,

thanks for a quick response. I use a PC and up until the ios & itunes update yesterday, everything was fine. I tried different USB port, USB cable and same problem. since i didn't want to downgrade my ios, i tried the easy route of downgrading my itunes, but that didn't work either, so I'm trying it on a different PC, and it does connect but i have a different problems w/ videos, so i'm playing on both to see which one wins out. i'll update this thread once i got this working. Thanks again for your prompt help ! You guys are great.
