IM+ Messenger is one of the most popular IM apps for BlackBerry. The developers, Shape Services, have gone to great lengths to continually support BlackBerry and its users. IM+ has come a long way over the years and is now available on multiple platforms including BlackBerry, Android, Windows Phone and iOS. With the latest release across all these platforms, IM+ features its own cross-platform messenger called “Beep”.

Beep is a free alternative to SMS and MMS and is much like the other cross platform messaging apps out there. The difference, is that it leverages Shape’s already 17 million users. The IM app also features sent and delivered features like in BBM.
