Do bear in mind, however, that there are some missing features in this particular first revision. Not only that, you will not enjoy any kind of voice messaging options, while there will be no chat heads hanging around which allows you to quickly alternate between active discussions.

This is all pretty much a whirlwind development, considering how it was announced at the recently concluded Mobile World Congress in Barcelona, Spain, that Facebook Messenger would be heading towards Windows Phone. Who would have thought that it would have been so soon? [Press Release]
