My iMessage has NEVER reflected my phone # on my iPhone 4s.
I have upgraded to all the latest iOS 7 versions including the iOS 7.0.3 and I still don't see my phone # appear with my email addresses. In fact, I routinely get the "An error occurred during activation. Try again." error message. I have followed ALL suggestions posted to this Discussion forum and nothing seems to work. I thought this was supposed to be fixed with the iOS 7.0.3 upgrade version. You would think a global company the size of Apple would have the resources to get this bux fixed.....GET IT RIGHT APPLE!!!!!!
