IM+ was initially launched for WP7 few weeks ago, with support for Chat in Facebook®, Skype®, Yahoo!®, GTalk™, AIM®, Jabber, ICQ® and MySpace™!
Now, with version 1.1, they added chat in Windows Live Messenger.. making this the best IM offered for WP7 to date (although KIK is smoother, but i only have 1 friend using KIK.. i dumped it)
'Always-on' communication across most of public messaging systems
Stay in touch with your your friends in a single buddy list right on your Windows Phone. Anytime, anywhere. IM+ offers ultimate mobile IMing experience with its sleek and polished interface.

First multi-messenger application for Windows Phone is finally here
IM+ does not limit your daily IMing to one-on-one chats. Keep in touch with your friends and colleagues in Skype group chats. We will be adding support for other group messaging services in forthcoming updates.
