ummm You can have the camera flash go off when you get a notification or phone call.... There is no option to have a little green LED light up when there is a message waiting tho, that's a Blackberry feature.
If you're interested in the flash+ringtone/vibe:
Settings>General>Accessibility>LED Flash For Alerts
