I can't get my iPod touch to connect with iTunes. Every time I enter the passcode, it never gets past the verifying part, then eventually the numbers clear and I have to type it in again; it's the same thing over and over. I've tried making sure the firewall is not blocking and I don't even have firewall on. My computer and iPod use the same wireless router connection. All the remote settings for iTunes are correct so I don't know what's the problem. Can anyone give me some advice?
