I'm stuck w iOS7.1.2, I don't want to pay $600+ for another phone that will do almost exactly what the 4 does. Now that I hear that malicious coding can ride inside a Tiff image within a text message, how do I turn off receiving any pictures in text messages in iOS7? I am told to turn off SMS. If so, what stops iMessage from displaying picture text messages? I do not want pictures any longer in text messages, ONLY TEXT.
