Hi, I upgraded my iPad 2 to iOS7 which went well. I connected the iPad to iTunes to back up the iPad. It was wanting me to sign in. Discovered that the laptop iTunes and the iPad iTunes have two different log-ins. Have changed the password on the iPad via the email download. Every time I try to log in it says it cannot connect due to a server error. It is connected to the internet and is functioning. This has been going on now for over a week and I am ready to throw the iPad out of the window. Please can someone help me with this, I am tearing my hair out! How do I get the two to work together?
