It's a small version bump going from 3.4.14 to 3.4.16 with no change log from Google but everyone is used to that by now. Forum users are now reporting
that the voice lookup function does indeed now work on the BlackBerry Tour. So if you are a Tour owner this may interest you the most, all other users not exactly sure what else (if anything) has changed but if you are an avid user might wanna grab the download just to be up to date. Visit m.google.com/search
on your BlackBerry's web browser to grab it!
