I swapped my mothers old Iphone4 to an Iphone 5 and as I have done many times before on my own phones did a backup activated her new phone then did a restore. This time Imessage is doing something strange. Her messages does not show pictures, they show for a second then goes away and says downloading. They never show up, but if she hits details they are there. Also she does not see show older messages she has to go to message show message group by name and the older messages are there. I have never seen messages act this way. I had her turn messages off and back on restart phone and all didn't resolve the issue.
