We bring our mobile phones everywhere and sometimes when you are somewhere in the dark and wish you would have a flashlight you can also use you BlackBerry to see in the dark. No, not just by using the display – you can use the internal flash which is much better (and you don’t need to buy any of the Flashlight Applications.
All you need to do is:
Open the Video Camera application (not the normal camera)
Press "space" to toggle it on and off.
Pretty easy and a really nice trick to do more with your BlackBerry than just make phone calls.
