Do you find the Nokia 5800's built-in Notification Light feature for missed messages/calls actually quite hard to notice? Then LightSignalPlus from PhonePhreak Software is just what you need: it makes ALL THREE KEYS flash every 2 seconds whenever there has been an SMS or a call. LightSignalPlus has been designed to have the keys blink only when it makes sense. I.e. when a message arrives while you are currently in an app, LightSignalPlus assumes that you have taken notice, so the keys will not blink. LightSignalPlus activates the blinking only when there are no app windows open.
