I wish I could! Somehow during the update, I got signed out....now my phone won't let me sign back in. It says "waiting for activation" whenever I go into Settings, Messages, iMessage. Then below that it says use your Apple ID for iMessage. It makes it look like all I have to do is sign in with that and my password and Im good. But it never works! It just spins for too long then tells me "Could not sign in. Please check your network connection and try again." ARGH!!!!
Thanks though! It looks you have already helped others with this problem!
