iMessage iOS 7.0.2 problems ongoing... iPhone 5 updated to iOS 7.0.2
Had performed following steps last week:
1) Settings > Messages > iMessage - Off
2) Restarted iPhone
(It was in this manner that I was able to see all the messages that had previously shown a sent "successfully" show up and "Not Delivered")
3) Settings > General > Reset > Reset Network Settings
4) Settings > Messages > iMessage - On
Just last night, noticed iMessages reaching a device running iOS 7.0 that was not delivered to my iPhone 5 that is running iOS 7.0.2.
Let us think about how this plays out. If you are using an iPhone currently, you send a message that you *think* goes out okay, but the other party has not necessarily received it. The opposite can occur for a message that someone else has sent to you. Pretty much the basis of a communication breakdown. For your listening pleasure:
