We first caught wind of Kik Messenger for Windows Phone 7 during MIX11. At the time, it wasn't too clear when the popular messaging service would be available on our platform i.e. pre-Mango or during Mango launch?
Now it looks like they've answered on their Facebook account--all it took was someone to ask:
Alejandro Aguilera Rivera: Are you guys (by any chance) working on a Windows phone 7 app? is it possible? :D?
Kik Interactive, Inc.: You will see it within a month :)
So that sounds good to us. In fact, the race between IM+ and Kik seems to be heating up as we're expecting releases from both companies relatively soon, giving Windows Phone users some new options. Not to mention, there's that whole Mango-Live Messenger/Facebook Chat integration coming too.
