Hi Everyone, I've been using iPad for six months now and love it. Recently though it has refused to let me sign in to FaceTime and iMessage. The error message is : Could not sign in. Please check your network connection. I know I have network connection since I can use Safari. I know I've got the right Apple ID and password because I can open my Apple ID account through the Internet. I have read other forums where changing the DNS settings to google's; and checking the time on the clock is recommended, but no change! Any ideas? Thanks.
