I’ve been using an iPhone for years now and I still can’t type text messages very quickly on the screen. But with HeyTell I don’t have it. I can speak messages and send them to someone else who also has HeyTell. Then they can just hear my voice. If we both have the app open, it works like a walkie-talkie. You can even send your location and it works over 3G, so it is like walkie-talkies with unlimited range.

could this be used with an iPad?
I’d image so. Why not just try it?
Am I missing something here, or couldn’t I just record my voice snd send the recording via mms ( I already know people who do it on iphones) ? Why then would I want/need this software ?
You are missing something. Try the app. Your method would be very difficult to use to have a conversation.
This is why I get your newsletters and follow and friend you everywhere. Thanks again for your intel. :)
