Hi, I just installed iOS 5 on my iPad 2. I keep getting the notification "Cellular Data Account" when I try to access the web. I click on "Now" and and I get "Cannot Open Page", I never got this with iOS 4. I'm in New Zealand on Telecom XT network and I have full reception. I got a error message "No carrier update" or something like that when installed iOS 5. I bought the iPad up front so its unlocked. If anyone can help me it would be appreciated!
