We’ve posted about the Flash Light application that now offers support for the new HTC HD2 but now a similar application surfaces with same functionality/

With the limitation that it currently does not support “brightmode”, Flash Light has a dual mode of operation: for the LED to remain on whilst your finger is in contact with the screen, just press and hold but if you double tap, the LED will remain on till the next double tap. To exit the application all you need to do is tap near the top edge of the screen.
