Wife just got a new ipad mini. She has an iPhone 4 with ios 5. I have a iPhone 5, and ipad 2 (running ios 6). I set up a new apple ID for her ipad. iMessage working ok to that gmail, which I associated with iMessage. Is there a way to associate her iPhone cell number with that new ID so she can be receiving the same messages on her phone and ipad? Or can we go back to the common/old apple ID, but use only her cell phone number on both for her? Been playing with this for a couple of hours, but I thought a question here might help. Thanks.
