So just moved, have a new ISP/modem/router. Tried to download latest iOS to the iPhone, went all the way thru the 60 minute download, then threw a 'corrupt' error. Tried to un/reinstall iTunes, it will appear to download the .exe, but won't open/run it. Disabled driver signing, uninstalled Comodo firewall, checked router firewall settings, made a new user account and tried that. Nada. Thoughts??? Dell lappy w/64-bit Vista. tks.
