I have an iphone 4 and the new ipad and ever since I got the ipad my texts to various people end up going to multiple people at the same time even though it is not a group text. When I sent a text to my son his photo shows up as the sender and my wife gets the text at the same time. When he responds it also shows his picture and goes to both parites. I can't find anything in settings that would cause this. Any thoughts
