i was thinking about this the other day while driving...i have a friend whose old crappy phone had a built in speech-to-text SMS application, but yet the iPhone doesn't have one. the only speech-to-text app i've seen is for the Notes application. is there such an app for SMS so that you can speak into the phone and the app will write the text for you? if one doesn't exist i'd be really surprised. but if it does, i haven't seen it.
