The Google Mobile App for thehas been updated to support two new features. Firstly, it now supports searching by voice; you just hold the phone to your ear, say what you are looking for, and it will search for you. You don’t even need to press a particular key to start the search process.
Also, they’ve added Search with My Location for both devices, which will provide a location based specific response to the search. Obviously for this to work you need to have Location Services enabled on the device, and allow Google Mobile App to be able to access it.
More information direct from Google here, although it should be pointed out it the voice search works best with US accents right now.
