Back at the end of last summer RIM and Rogers Wireless made Yahoo! Messenger available to BlackBerry users on the Rogers Wireless network up in Canada. Today we are happy to announce that Yahoo! Messenger for BlackBerry is available on all carriers.

I haven’t heard any rumors but I wonder if AOL Instant Messenger and / or MSN Messenger will be coming out with free clients for the BlackBerry anytime soon? There seems to be a persistent battle for top dog IM Client. Google Talk for Blackberry and now Yahoo! Messenger have a bit of an advantage now that they have free clients for BlackBerry.

You can download Yahoo! Messener for BlackBerry directly from your device’s browser by visiting http://mobile.blackberry.com.
