Looks like we will be getting an alternative to Messenger by Miyowa soon. IM+ All In One Messenger, originally expected for a January-February release, is nearly complete and a beta version (don’t know what that means) is due in April. Although the updated version of Messenger is working pretty well, with a live tile and toast notifications (although a bit delayed), choices are always a good thing. I used this app on my WM 6.1/6.5 devices and found it to be stable and reliable. Will keep a lookout for the release in Marketplace (or the wild if it is really going beta first). You can find news and updates on the developers site here.
