I update my iPhone to iOS6 and my Mini to 10.8.2. After doing so, my iPad stopped receiving messages even though my phone and Mini still are. Is there something I need to change on an iPad running iOS 5 to get it to work again?
I also have an original iPad (WiFi only) and cannot get messaging to work on it either. It used to work, but I cannot remember if that was when I had AT&T for my iPhone. I now have Verizon for my iPhone 4S. If anyone has a solution, I would be interested in it.
