Multiple IM client application Nimbuzz has been updated to v2.4. This client now has closer ties with your smartphone’s address book, adds kinetic scrolling throughout the interface for touch enabled devices, has finer options to control Twitter update, and the ability to limit usage while roaming. More below.

There’s also a cute viral addition that lets users promote the application by choosing to send free SMS invites to their friends to get them to install Nimbuzz – which helps both the existing users to get to their friends, and has a knock-on positive effect on the uptake of Nimbuzz.

As well as the headline changes, minor bugs have been fixed, there are tweaks to the interface and performance updates throughout the code have been applied.

You can download Nimbuzz from get.nimbuzz.com.
