Two big breakthroughs have been announced over on the official Google Mobile Blog.  The first is that Google Search by voice is now available on all Nokia S60 phones which means whether you are a fan of the E or N Series you can finally skip the 12-digit keypad and submit your search by speaking into your phone.  The second big announcement is that Google Voice by search now supports Mandarin Chinese on Nokia S60 devices as well.  Unfortunately support for Mandarin Chinese is not available on other devices at the moment but Google vows to add the new speech recognition to products on other mobile platforms including Android and iPhone very soon.
