Sadly, not yet. I've got a BB Storm and have been waiting for a while.

Last I heard as of 4/9/9:

Hello,

At this time, the Battle.net Mobile Authenticator is only available for iPhone users. Blizzard plans on having this application available to other mobile devices and phone service providers in the future. Please check the website periodically for future updates. Thank you for your patience and understanding.
