This is great: Dragon Dictation has come to the iPhone, a superb solution that lets you speak your text/emails into your Apple mobile. This App is powered by Dragon Naturally Speaking – the same highly-effective speech to text engine which powers MacSpeech (itself a life-saving product for many, particularly those with damaged/broken arms). How it works:
