Google Mobile App for Blackberry, now lets you search with your voice and with My Location. Just visit http://m.google.com on your Blackberry. It now supports British English, and is available on all versions of Blackberry running on O/S 4.1+ and with Search by voice on O/S 4.2 and above, although the Blackberry Storm is not supported at this time.
With My Location feature enabled, just enter a "search query" into Google Mobile App, and it will return the resutls. And Search suggestions appear as you type, saving you keystrokes and time. Searching by voice can be used in combination with the My Location feature, and it works well with standard Google searches, such as currency conversion and weather. Just press and hold the green button in Google Mobile App.
