Yahoo! Front Page
is the java/internet version, I found it on the Yahoo Messenger site Blogs (search on Blackberry). I have to use it as there is a problem with the latest version of Blackberry OS (4.2. something) and latest Yahoo Messenger 2.0.33 (1.095 works on 4.2.something but not latest version).
It is pretty disappointing that a download from Blackberry itself does not work on its latest OS. The application installs but the icon does not appear on the application list. Blackberry really sucks I have to say.
I noticed this site translates the above address into a link, the site address for your Blackberry is m.yahoo.com
(add the http:// before and / after yourself).
