Looks like its time to turn up the heat when it comes to instant messaging on the Nokia N9/N950 (MeeGo Harmattan). Here we have TalkBox Messenger that basically allows you to send Voice messages to each other, saving you the pain of typing.
Simply "Hold to Talk", "Speak", "Let Go" ... and your DONE !
I've had a quick play and it seems to work REALLY well. This is an application that does warrant further investigation which it will get soon. Cross platform so you can chat to your iOS and also Android buddies as well.
VOICE MESSAGES REDEFINED!! EXPERIENCE A NEW WAY OF MESSAGING!!
