Hope someone can help me I have had my iPhone 4 on AT&T since release and never had a problem like the one I am having now. This weekend I tried to send a couple of pics to someone and i realized that they didn't go through. All i kept getting was the (!) next to the picture. I sent a pic to my girlfriend same thing and she's on my plan (she has a Nokia Lumia 900). I went and restored the phone..... nothing. Did a network reset..... nothing. I also made sure that my mms was turned under settings>messages>mms on. It just stopped working over night. I'm hoping someone here can help. I'm on firmware 5.1.1.
