iPhone 4 causes iTunes to lock up during backup
So, this just came out of the blue. I went to sync my iPhone 4 and it refused to make it past the backing up, much less sync. I tried uninstalling/reinstalling iTunes, deauthorizing and reauthorizing, and now iTunes won't even recognize the presence of my phone, although it will open iTunes automatically which then locks up and quits responding and does not even attempt to back up any longer. Pulling my hair out here....what do?
iPhone 4, Windows XP
