Research in Motion has released updated clients for Google Talk and Yahoo! Messenger. I don’t use Yahoo! Messenger, however, the new Google Talk version 2.0.38 doesn’t seem to do anything different the the previous update, 2.0.35. My guess is that these new dot releases are just fixes to bugs reported in earlier versions.
Unfortunately we have to guess because RIM doesn’t include release notes or “whats new” documents with these apps.
Anywho, if you would like to get the latest versions of Googe Talk for BlackBerry or Yahoo! Messenger for BlackBerry, head on over to mobile.blackberry.com
