Has anyone tried this app with their iphone4? May work with the 3GS as well, but not sure. It's a free app in the app store and boats a 4 out of 5 star rating. I just downloaded it and it seems to take dictation pretty accurately, syncs with your phone book, twitter and Facebook accounts pretty effortlessly too. Pretty cool being able to speak your updates, instead of typing them in. For those looking for a substitute Siri-like app, since if you're like me and can't upgrade to the 4s, this may be for you. I'm kinda digging it.
