A new easy to access Flashlight feature has been discovered in iPhone OS 4.0 beta 4.
It's unclear if this is an actual feature or a bug; however, triple pressing the lock button while viewing the lockscreen will turn the entire display a bright white. Pressing the button once more returns you to the lockscreen.
If the screen is off a double tap will bring up the white background.
