don't know if this helps but this started happening to me from only one friend with iphone, and i think it started happening after i sent him a pic (mms), so i always thought it was because he was replying through that mms when he sends me a text and that's why i receive it as mms (which happens even if you are not on iphone). Some of his texts are sms still though so i thought it was how he is sending text, whether he choses to reply from mms or sms.
