what does the magnifying glass do?

[ienjoysoup08]

I don't have my evo yet (have to wait tell july) but I was wondering what the magnifying glass button on the phone does. I know you search stuff but what if im on the home screen and I press the button what can I search besides google?

If you tap it once, and start typing, it will search your entire phone for matching items.

If you tap and hold, it allows you to speak a Google search.
