Popular instant messaging app IM+ was updated to version 6.4 last week, bringing the interface up to date with newer versions of Android and adding new features like Rage Face emoticons.

IM+ is popular with users due to its features and the wide ranges of services it can connect to. Google Talk, Facebook, AIM, ICQ and Jabber are just a few of the features the app supports. The new update brings two new services to the ever growing list: Gadu-Gadu and MeinVZ.

Version 6.4 of IM+ brings some very useful new features in addition to the fun but not so useful Rage Face emoticons. Sleep Mode, for example, is a new feature that allows you to select a time range when you won't be bothered with notifications.

Users can now bulk export chat history to an SD card, which is very useful if a chat contained important information that you want to make sure isn't lost. Other new features include the option to further customize notifications and the option to automatically start “off-the-record” messaging.

IM+ has also improved its interface, claiming that it “feels like Ice Cream Sandwich.” While the UI is definitely better for users of Ice Cream Sandwich and Jelly Bean, the app isn't fully Holo-themed.

The day after IM+ was updated to 6.4, another update followed, bringing the version number to 6.4.1. This is a maintenance release comprised of crash and bug fixes.

IM+ is a free download in the Google Play Store and works on devices running Android 2.1 and up.  Certain features are only available in IM+ Pro which will cost $4.99, but this version also removes ads and includes extra services like Skype, which is an in-app purchase in the free version of IM+.
