I had an interesting thing happen the other day.... My wife sent her mother an iMessage. Her mother received the message, but it appeared as though it came from MY fathers phone number. All parties use iPhones, but all have separate Apple ID's. The only connection is that my fathers phone is on our phone account. The message was sent and received as an iMessage. Any ideas? The only thing I can find about this is where people have shared an Apple ID, but that's not the case in this situation.
