Not new news but I wanted to post a link to the BlackBerry YouTube application that was developed by Google. For some reason people (including me) have a hard time locating it.
This client is awesome, full rich UI (not the mobile web pages.) It’s the most iPhone feeling app for blackberry.
Direct your Blackberry over to http://m.google.com/youtube and it should offer a version 1.6 or greater.
Also you can check out more by visiting there product page:
http://www.google.com/mobile/default/youtube.html
Only works for the BlackBerry Storm.
