The cross-platform multi-protocol IM app, IM+, has been updated to support Mango.
The app now supports fast app switching and the update also brings some bug fixes.
IM + supports Skype chat, Facebook chat, Google Talk, AIM/AOL/iChat, Yahoo!, ICQ, Jabber, VKontakte, Yandex IM and MySpace, but not Windows Live Messenger, at the request of Microsoft.
The app also supports Tile and Toast notifications and Push-to-Email to allow incoming messages to be forwarded to your email, meaning users are always available even if the app is not running.
IM+ by Shape Services is free and can be found in Marketplace here.
