New Versions were released over night for BlackBerry IM services. My update took me to version 2.5.27. The link below will allow access to all 5 (Google Talk, AIM, Yahoo Messenger, Windows Live and ICQ) for OTA download from your BlackBerry. Pick the one you want or currently us and download. Enjoy
Reboot is recommended after upgrade or new Installation.
From you BlackBerry go HERE to install OTA.
