I've got the same problem with my iPad. Cannot login to iMessage or Facetime.
I can login to FindFriends but after 5-20 seconds, it always displays a message saying that there is a problem with my apple Id and password and that sign in is required. This occurred with iOS 5 and nothing has changed with iOS 6.
Interestingly, on the same network, all this works with my iPod!
Surfing this and it appears it's a common problem. I've tried the DNS suggestions and setting date/time to automatic and still no go. Argh!
