Nimbuzz Messenger — that mobile messaging app that lets you chat with friends on Facebook, Gtalk, or Yahoo Messenger for free — has been updated for BlackBerry users.  The updated version requires less memory space and promises faster file transfer and better connectivity on slower networks.

Nimbuzz includes multimedia sharing, social network integration, free chat rooms, and chat buddies.  The new version also adds user interface features such as bubble chat and contact list separation, offline message queuing, and three-second contact list loading.  Nimbuzz supports phone number verification, so you can quickly find your existing phonebook contacts that are already using the platform.

Nimbuzz  claims 150+ million registered users across different platforms, and the app is available in 19 languages — the most popular being English, Spanish, French and Arabic.  The new version of the Nimbuzz is available for download in BlackBerry World.
