For some reason my blasted phone doesn't do MMS. It just doesn't. It'll hang on the "sending" stage for a while, and then give me the red circle with the exclamation mark next to it, and the option to try to resend the message. If someone else tries to send me a picture, it appears to send on their phone, but just doesn't show up in mine. The text just doesn't arrive. There's some blockage between my phone and MMS. The MMS is turned on in Settings, and I've reset network settings as well. Why is my phone doing this? It's a non-jailbroken phone running on AT&T, and I'm in one of the best cities for reception in the country.
