I updated yesterday (after about 10 tries to activate). Today I am trying to use some of the apps that I don't use everyday. Why so difficult? iMessage wanted me to sign in with my Apple ID and password. So I did and I get the message that it can't connect and to check my network connection. It is fine. Anybody else having this issue? Any ideas how to get this to cooperate? Maybe its still the Apple servers overloaded, but sometimes someone has figured out a way around an issue.
