"itunes could not connect to the iphone because an invalid response was received"
i cannot sync my iphone 3g. every time i plug it in, i get the response, "itunes could not connect to the iphone because an invalid response was received from the device."
I am running windows vista 32bit, firmware 2.1, itunes 8.... i turned off all firewall protection and virus scanning and uninstalled and reinstalled all programs to no avail. i updated my usb drivers and my bios but it still does not work. :doh:
can anyone help with this issue? thanks!
