Hello all I am currently in Iraq and have been using my ipad2 to talk to my girlfriend at home on her iphone 4S. We use the iMessage app but as of about a week ago it has quit working. When I send a message it acts like it goes through but the little word that says "delivered" doesn't move to the bottom of the list. She isn't receiving them on her end. When she sends me a message it comes through to my email. I have reset mine and signed off of the imessage and signed back in. She has done the same on her end with the iphone. Has to be something simple we are missing. Can anyone help please? Thank you!
