How to change Android device's default search engine? I am trying to play with Android...To change the default search engine (now is Google, or add more selectables) when I press the "search" button on the device.

Is there anyway to do it? I have HTC Hero and HTC Desire, already rooted
Not currently possible. It's not locked in to Google, but determined by manufacturer and/or carrier. (For instance, there was a bit of a tempest in a teapot when a new phone was released with Bing as the search engine.)

I do not know if this is something that can be got around by rooting.
