Accessing old iMessages on a new iPhone
I just got a new iPhone 5s today, but when I set up my iMessage on the phone I can't see any of my old conversations that happened on my iPad or Mac.
I first started using iMessage at Christmas when I got my iPad and when I started using it on my mac later, it loaded all of my past conversations straight away after signing in. I just don't understand why it won't work now on my phone. Can anybody shed some light on this?
PS, I can send and receive iMessages on all 3 devices, but I can't access old chats on my iPhone.
Thanks in advance for any suggestions!
