I have a very weird problem here. I just received three MMS from someone who is in my address book. (I know it's from this person because she had just called me and told me she's sending me three pictures). I have received SMS/MMS from her before and it always worked as it should. All three messages that I just received displayed a From number that is not recognized. I tried calling one of them, to see what would happen, and a real liver person answered. I didn't know what to say, so I just told him I have the wrong number. She says she definitely used her own phone to message me. What is going on? I searched the Apple forums, and there seems to be a small number of people with the same issue. Anyone here having this problem?
