iMessage Cannot Connect to Server
I upgraded last week to the iPhone 4S from the iPhone 4. I deactivated the iPhone 4 in iTunes. Now I'm trying to get iMessage turned on in the new phone and it keeps returning an error that it could not sign in, and to check my network connection and try again.
I've tried this on 3G and wifi. My connections are fine.
Is the iMessage server down? My password is correct, too.
What's stopping this feature from turning on?
