i am using Windows Vista with my 1.1.2 iPhone & iTunes 7.5
iTunes cannot detect my iPhone when i plug it via the USB cable to my computer, while Vista can detect it and i can access the photos inside iPhone with the link my computer\Apple iPhone\Internal Storage\DCIM\100APPLE.
the interesting fact is that when i turn off the "program control" (a function in my firewall, ZoneAlarm). iTunes can then detect the iPhone can they can sync(ringtones, music, contacts successfully get into iphone)!
if i switch on the "prgram control" in zonealarm after they sync, disconnect iphone and reconnect it, an error message will be shown, something like "iTunes cannot connect to iPhone [^2], unknown error (0xE8000001)"
if you know what happening, please HELP!!! thanks for your time!!!
