Hi, For some reason when I got my 5S and installed my backup copy from my iPhone 5 on it, I started to miss a lot of messages on my phone. I've been in the settings for iMessage and confirmed that I have both my phone number and my email address enabled. But for some reason they still don't come in on my phone. On my friends' devices they now have 2 threads after I got my 5S, and only one of them works for me now. I even tried sending a group message from my 5S, and for one of my friends it landed in the old thread (meaning that when he responded I wouldn't receive it on my phone), while the other friend got the message in the new thread. What the hell is going on?
