I thought one of the features of iMessage was that I could have a conversation on my iPhone, then continue it on my iPad. Or vice/versa. I can send an iMessage from my iPad, and then I can also get a response on my iPad. But if I start on my iPhone, the iPad doesn't show any of it. I have checked my settings. When I look at "Receive At..." the Apple ID is the same on both, the iPhone has 4 addresses, the iPad has 3 addresses. The only difference is that the iPhone has my phone number plus the 3 email addresses. Any other settings I'm missing or did I misunderstand that you could pick up on a different device in the middle of messaging?
