TalkBox launched a new BlackBerry Smartphone client in beta last week and it seems to be working nicely. The apps allows you to send voice messages back and forth in an instant messaging fashion. In other words think of it as a walkie talkie service that works cross platform from iOS, Android, Windows Phone and now BlackBerry.
Check out the beta at this link as long as you have OS 5.0+ and an SD card. Thanks Terrence for pointing it out!
