RIM is on an updating roll bringing all the IM clients to 2.5 with some new features. Apart from being OS 5.0-compatible, the new clients feature deeper integration with BlackBerry address book contacts, conversation search function, and better emoticon selection.
There is also a new feature that allows you to save a favorite contact as a home screen icon for even faster navigation.
